The correct answer is: C. Was / was
The first blank should be filled with “was” because the sentence is in the past tense. The second blank should also be filled with “was” because the subject of the sentence is “she,” which is singular.
Option A is incorrect because the second blank should be filled with “was” instead of “were.”
Option B is incorrect because the first blank should be filled with “was” instead of “are.”
Option D is incorrect because both blanks should be filled with “was” instead of “was” and “were.”
