Answer Details

The correct option is "was being questioned". The sentence is in the past tense, which means that the verb should also be in the past tense. The verb "to be" is conjugated as "was" in the past tense for the singular third-person subject "suspect". The word "being" is the present participle form of the verb "to be", which is used to form the present continuous tense. Therefore, "was being questioned" is the correct form of the verb to use in the sentence.
