Hello himanshu0123,
We hope this finds you well.
To answer your query, the subject of the sentence is "researchers" and the main verb is "have been able".
Further, the object of the sentence is "the amount of protein"; "Employing the same techniques used to genetically enhance plants so that they are disease- or pest-resistant" is, in its entirety, the modifier that acts upon "researchers".
We hope this helps.
All the best!

In Answer choice C, I have a few issues
1) "they" seems ambiguous. "they" can refer to both techniques and genetically enhanced plants". Also they is the subject so it should refer to "techniques". Why then is it referring to "genetically enhanced plants"
2) the techniques are used to enhance plants to make them disease and pest resistant. But in option C, the meaning is changed to say that they are disease resistant. Is meaning change allowed?
Kindly explain

Yeah they can theoretically refer to both techniques and plants. However, pronoun ambiguity is almost never a reason to eliminate an answer choice.
By the way, techniques is not really the "subject"; if anything techniques is the object of the verb-form employing.

Not sure why you think C changes the meaning. It is saying that in order to make plants disease- or pest-resistant, researchers are employing the same techniques used to genetically enhance plants.
