• A. Whereas in mammals the tiny tubes that convey nutrients to bone cells are arrayed in parallel lines, in birds the tubes
• B. Whereas the tiny tubes for the conveying of nutrients to bone cells are arrayed in mammals in parallel lines, birds have tubes that
• C. Unlike mammals, where the tiny tubes for conveying nutrients to bone cells are arrayed in parallel lines, birds' tubes
• D. Unlike mammals, in whom the tiny tubes that convey nutrients to bone cells are arrayed in parallel lines, the tubes in birds
• E. Unlike the tiny tubes that convey nutrients to bone cells, which in mammals are arrayed in parallel lines, in birds the tubes

Answer 1

The correct option is A Whereas in mammals the tiny tubes that convey nutrients to bone cells are arrayed in parallel lines, in birds the tubes

Option A is a correct option as no errors as showing proper comparison.

Option B is not correct as tiny tubes are compared to birds, moreover, usage of voice should be parallel.

Options C and D are also gone as mammals are compared with bird's tubes. Unlike should always be followed by nouns.

Option E is also wrong as "Unlike" can not distinguish between a noun and a phrase.

So, Option A is correct as the comparison is logical.
