the modifier "unlike most warble species" should modify some species. But it is not doing so in any of the options ABCD

E reframes the sentence clearly distinguishing out Blue-winged warblers from most species of warbler

hence E

Unlike those in most warbler species, --> this signals now we are going to talk about some specific warbler species which does not have the quality 'those in'
The sentence which follows does not explain about any specific warbler species.
Moreover IMO 'those in' does not seem to be correct usage.

Ambiguous pronoun: What plural noun is being replaced by the pronoun those?
Parallelism: the construction those in should be compared to another noun + in construction in order make a parallel comparison
Meaning: The use of to distinguish makes the meaning unclear. Are we distinguishing between the male and the female or between the male and female warblers and other species?
