The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options. If you don’t find any error, mark ‘No error’ as your answer.
Frank has being making / the rounds, advancing a theory / that I believe is not without merit.

Correct option is C

Option (c) contains an error.
Explanation: The phrase "has being making" is incorrect.
The correct phrase should be "has been making."
"Has been" is the present perfect continuous auxiliary verb, while "being" is a gerund or passive auxiliary, which is incorrect in this context.
Grammatical rule used:
· "Has/have been" is used with present perfect continuous tense (Subject + has/have been + verb-ing).
· "Being" is used in passive constructions, which does not fit in this sentence.
Example:
✅ Correct: He has been making a lot of effort to complete the project on time.
❌ Incorrect: He has being making a lot of effort to complete the project on time.
