In the Explanation above Mike Mc Garry sir has told that whereas should follow a Clause (SV Pair), but the correct answer choice A has Whereas IN..., IN....

Isn't that requirement of SV pair immediately after whereas breaking.

Hi Richa,

Happy to help :)

Whereas in mammals the tiny tubes that convey nutrients to bone cells are arrayed in parallel lines, in birds the tubes form a random pattern.

We do still have to full independent (SV) clauses here -- it's just that they are both prefaced by "in mammals/birds." This is okay:

[in mammals] the tiny tubes (S) that convey nutrients to bone cells are (V) arrayed in parallel lines

[in birds] the tubes (S) form (V) a random pattern.

It is okay to have a prepositional phrase as the beginning of the independent clause.
