a. past progressive

b. present progressive

c. past perfect progressive

d. present perfect progressive

If you need to find the tense of the verb had been going, then the correct answer is C. past perfect progressive.

This tense is formed in the following way: past perfect of the verb to be ( = had been) + perfect participle of the verb you need (it can be found in the third column of irregular verbs, or when it comes to regular verbs, you just add - d/-ed to the base of the verb).

Past progressive would be was going, present progressive would be is going, and present perfect progressive would be has been going.
