Question

Identify the form of Present Perfect Continuous Tense:

• A. Subject + had been + verb + ing
• B. Subject + have been + verb + ing
• C. Subject + had been + base form of the verb
• D. Subject + had being + verb + ing

Answer 1

Answer: (B)

Subject + have been + verb + ing

This tense is generally used to describe or indicate an event that is going on at this moment. The present perfect continuous tense is made up of two parts: the present perfect tense of the verb ‘to be’ (‘have been’/‘has been’) + present participle of the main verb (ing form). Thus, B is correct.
A is incorrect as present perfect does not take the past form "had been".
C is incorrect as present perfect takes the present participle or the ing form of the verb and not the base form.

D is incorrect as "had being" is grammatically incorrect.
