143. Recently discovered fossil remains strongly suggest that the Australian egg-laying mammals of today are a
branch of the main stem of mammalian evolution rather than developing independently from a common
ancestor of mammals more than 220 million years ago.
(A) rather than developing independently from
(B) rather than a type that developed independently from
(C) rather than a type whose development was independent of
(D) instead of developing independently from
(E) instead of a development that was independent of

[stop@800]

IMO B

Gmat always prefers rather than over instead of
so we can rule out DE

Australian egg-laying mammals of today are AAA rather than BBB
here AAA and BBB should be parallel

AAA is A branch......
so we need a type
so A is out

out of B and C
B is more clear and concise
it says "developed independently from"
which is the correct usage

[raunekk]

imo:B

[andy9590]

[vivek.kapoor83]

[nervesofsteel]

B is the best..
