What is the correct answer ? I feel D cud be correct ?

California condor is singular.

A & B out

C maintains parallelism.

in D the second about is redundant

My doubt is daily movements, foraging habits, are charactesitcs that can be grouped together whereas nesting sites is not so .. it is about a place where they nest rather than somekind of habits .. parallelis cud have been used here if we are talking about nesting habits rather than nesting sites ....


Could you please explain

Same here I feel C is correct...

c is parallel …..and condor is singular ( so its)

D - about nesting sites, i am not sure if about is needed it wordy ....

(c) is apt.

Plugging in option (c) makes the sentence -

The study undertaken by Department of the Interior will involve examination and tagging of the California condor in order to obtain information about its daily movements, (about its) foraging habits, and (about its) nesting sites.

the daily movements, foraging habits and nesting sites - these are all the information that the study undertaken by the Department will involve itself in.

Hope it helps, thanks.
