A should be for correct comparison.

IMO: A as well, but is usage of whereas correct?

Inappropriate comparison btn MAMMALS and TUBES in C & D - drop them
E - its would have been better to have THE TUBES after comma to make the comparison btn TINY TUBES...TUBES clear; WHICH could refer to BONE CELLS, making the meaning non-sensical
B - apart of the issue of not placing TINY TUBES and TUBES in parallel position, the 2nd clause BIRDS HAVE TUBES...convey a state while the first clause (TINY TUBES..ARE ARRAYED) convey an action; Use of THAT ARE ...makes the sentence wordier as well

IMO A
The use of WHEREAS...makes it as a dependent clause (just as THOUGH/ALTHOUGH)
