A Correct answer
Explanation

Sideroxylon grandiflorum is a long-lived tree in the family Sapotaceae, endemic to Mauritius. It is also known as tambalacoque or dodo tree. It is valued for its timber. Stanley Temple hypothesized that the dodo, which became extinct in the 17th century, ate tambalacoque fruits, and only by passing through the digestive tract of the dodo could the seeds germinate. Thus, due to the extinction of the dodo, the tree has become endangered. So, the correct answer is 'Sideroxylon grandiflorum'.

A Correct answer
Explanation

The California condor is a New World vulture, the largest North American land bird. It became extinct in the wild in 1987, but the species has since been reintroduced to northern Arizona and southern Utah, the coastal mountains of central and southern California, and northern Baja California. As condors forage exclusively on dead animals, they are especially susceptible to lead exposure from carcasses which are left in the field. Lead poisoning from spent ammunition is the number one cause of death among endangered condors in the wild.

So, the correct answer is 'Increasing pollution'.
