hi all..
Please help me with the issue. I am unable to judge the use of "having" /" having been" in sentences as correct or incorrect, and as a result have got a habit of simply rejecting the choices with the word. Now its pinching me again and again. So I want to finish the issue once for all.
So I request anyone "HAVING" confidence in the same to please explain the usage on GMAT.
Thanks in advance...

Having ends in -ing - it can either be a gerund (a verb serving as a noun) or the conjugated portion of the verb to have
Consider whether the action in the main clause of the verb follows the action listed in the dependent clause (i.e the clause with having)
Note have and has serve as helping verbs when reporting events in the past that happened in sequence.
He had eaten when we arrived -> sequence of events
Having drank a lot, she went to the bathroom. -> She drank AND THEN went to the bathroom
Having can not be alone in a sentence and must help a secondary verb, also there must be an independent clause which contains the working verb of the sentence
Unless Having is serving as a gerund, connoting "having" as the subject of the sentence
See : Having, is one of the most sensational feelings in life.
