Sentence Correction (SC) | Re: Visitors to the zoo have often looked up in to the leafy aviary

(A)saw macaws resting on thebranches, whose tails trail

(B)saw macaws resting on thebranches, whose tails were trailing

(C)saw macaws resting on the branches, with tails trailing

(D) seen macaws resting on the branches, with tails trailing
(E) seen macaws resting on thebranches, whose tails have trailed


We have two verbs in sequence "have looked and have seen"

So "saw" is wrong with "have".

A, B, and C are out

E is wrong for modifying error - "whose is wrongly modifying "branches" instead of modifying "macaws"

D. Correct - Prepositional phrase "with blah blah blah" correctly modifying "Subject of the principal clause".
