Valmik Thapar and Fateh Singh Rathore documented groundbreaking observations of male tigers caring for their cubs in Ranthambhore, proving they don't kill their own young. Their photographic evidence in the 1980s changed scientific understanding of tiger behavior. Jim Corbett was a famous hunter-conservationist from an earlier era, while Kailash Sankhala was known as India's 'Tiger Man' for conservation work.

To solve this question, the user needs to be familiar with the title and author of the book, "My Life: My Trees".

Option A, Joy Adamson, is the author of the autobiographical book "Born Free", which is about her experiences raising a lioness cub named Elsa.

Option B, Richard St. Barbe Baker, is the author of the book "My Life: A Tree Lover's Story", which is an autobiographical book about his life's work to protect forests and promote reforestation.

Option C, Konard Lorenz, is a Nobel Prize-winning ethologist and author of books such as "King Solomon's Ring" and "On Aggression", which are about animal behavior.

Option D, K.M. Tewari, is not a known author of the book "My Life: My Trees".

Thus, the correct answer is:

The Answer is: B, Richard St. Barbe Baker.

The Palaearctic realm covers most of Asia (including China, Russia, Mongolia, and Central Asia), Europe, and North Africa. It's the largest biogeographical realm, characterized by temperate forests and grasslands. The Oriental realm covers only tropical South and Southeast Asia, while the Nearctic covers North America and Neotropical covers Central and South America.

Black Ironwood (Olea laurifolia or Krugiodendron ferreum) is renowned for being one of the densest and heaviest woods, often sinking in water. Balsa is famously one of the lightest.

The Chausingha or four-horned antelope is unique in having four horns - two pairs between its ears. This small deer species found in India and Nepal is the only living mammal with this trait. The name 'Chausingha' literally means 'four horns' in Hindi. Elk have large branched antlers, blackbucks have spiral horns only in males, and bharal have simple curved horns.

India is the only country with both wild lions (Gir Forest lions in Gujarat) and wild tigers (found across several states). Asiatic lions are now restricted to Gir National Park, while Bengal tigers roam various reserves. Uganda has lions but no tigers, Pakistan has only tigers, and Zaire (now DR Congo) has only lions.

The Sociable Weaver of southern Africa builds enormous communal nests that can house hundreds of birds and weigh tons. These massive structures built on trees or poles are the largest individual nests of any bird species. Ostriches dig nest scrapes but don't build structures, while quelea birds weave smaller nests. Mountain drongos build typical small cup nests.

The Reticulated Python is the longest reptile in the world, capable of reaching lengths over 6 meters. While the King Cobra is the longest venomous snake, it is not as long as the Reticulated Python. The Emerald Tree Boa and Black Mamba are both considerably shorter in length.

The World Wide Fund for Nature (WWF) is the world's largest private international nature conservation organization, operating in over 100 countries. While organizations like the Audubon Society and Bombay Natural History Society focus on specific regions or species, WWF has the broadest international scope and largest membership.

Non-resident viruses operate in two distinct phases: a finder module searches for files to infect, and a replication module handles the actual infection. Unlike resident viruses that stay in memory, non-resident viruses don't remain active after infection. Trojans and worms are fundamentally different - Trojans disguise themselves as legitimate software, while worms spread independently without needing a host file.
