Choices

Choice-A

Choice A is incorrect because “we” is a first-person plural pronoun, used when the speaker is included in the group being referred to. Since the sentence is not written from the perspective of Linda Buck or Richard Axel, using “we” would wrongly include the speaker and is therefore inappropriate. Therefore, “they” (the correct third-person plural) should be used.

Wrong we

7

Choice-B

Choice B is incorrect because “one” is a pronoun used to refer to a single, unspecified person and is not suitable for referring to two specific individuals mentioned in the text.

Wrong one

8

Choice-C

Choice C is correct because “they” is the correct pronoun to refer back to Linda Buck and Richard Axel, the two biologists mentioned earlier in the text.
