Explanation:

Correct option is 2: part b.

The error lies in part (b): "if she had found".?

Explanation:

The sentence is structured as an indirect question introduced by "Can you tell me." In indirect questions, standard subject-verb order is used without inversion. The phrase "if she had found this job when she moved here" suggests a past perfect tense ("had found") followed by a simple past event ("moved here"). However, the use of past perfect ("had found") is unnecessary here, as both actions can be appropriately expressed in the simple past tense to indicate they occurred sequentially in the past.?

Corrected sentence:

"Can you tell me if she found this job when she moved here?"?

By changing "had found" to "found," the sentence maintains proper tense agreement, indicating that both events happened in the past without implying one preceded the other.?
