To determine whether the underlined verb is using the simple or progressive aspect, you need to look at the structure of the verb tense. In this case, the verb "investigating" is formed by combining the helping verb "is" with the present participle form of the verb "investigate." This is the structure for the present progressive tense, which indicates an ongoing action in the present.

Therefore, the correct answer is:

(Choice B)
B
Progressive
