Vitamin B7's chemical name is Biotin. It is a water-soluble B vitamin that plays important roles in fatty acid synthesis, amino acid metabolism, and gluconeogenesis. Dermatitis is actually a symptom that can result from B7 deficiency, not the vitamin itself. Option B is incomplete, and Option C appears to be a made-up term.

BMP stands for bitmap, which is a raster graphics image file format capable of storing two-dimensional digital images. A bitmap is a mapping from some domain (like a range of integers) to bits, allowing for the representation of monochrome or color images. Options A, B, and C are all incorrect variations that don't match the standard terminology.

EXE stands for executable, which refers to a file that contains a program that can be run by the operating system. These files contain machine code that the computer's processor can execute directly. Option A incorrectly uses 'extended', while Option C uses 'executive' and Option D uses 'explainatory' - neither of which are correct.

Vitamin B9's chemical name is Folic acid (or folate in its natural form). It is crucial for DNA synthesis, amino acid metabolism, and cell division. Option A appears to be a misspelling, while Option C incorrectly suggests 'Aldehyde' as part of the name. Folic acid is especially important during pregnancy for preventing neural tube defects.

Vitamin B12's chemical name is Cyanocobalamin. It is the most common form used in supplements and fortified foods. Vitamin B12 is essential for red blood cell formation, neurological function, and DNA synthesis. Options A and D use incorrect spellings ('Cyano-6-12' and 'Psyanocobalamin'), while Option B is not a valid chemical name.

Vitamin C is scientifically known as ascorbic acid, a water-soluble nutrient essential for collagen synthesis and antioxidant function. Folic acid (option B) is actually Vitamin B9, not Vitamin C. Options A and C are incorrect - 'Ascorbous acid' is a misspelling, and 'Cynopsys-C' is not a real compound.

Vitamin D exists in multiple forms, with ergocalciferol (Vitamin D2) being one of the primary chemical names. Options B, C, and D appear to be fabricated or misspelled terms - 'Dentalocobalamin' and 'Dermatocobalamin' are not real compounds, and 'Dergocalciferol' is a misspelling of ergocalciferol.

Vitamin E refers to a group of compounds collectively called tocopherols and tocotrienols, with alpha-tocopherol being the most biologically active form. Options A and B incorrectly prefix tocopherols, while 'None' is not accurate.

Vitamin K's chemical name is Phylloquinone (also called phytomenadione or Vitamin K1). It is a fat-soluble vitamin essential for blood clotting and bone metabolism. The other options (Quamoquine, Chloroquin) are incorrect or fictional chemical names.

The Amazon Rainforest is the largest rainforest in the world, covering approximately 5.5 million square kilometers across South America. It spans nine countries and is home to incredible biodiversity. The Congo Rainforest is the second largest, while Atlantic and Cape York are not major rainforests.
