GMAT Sentence Correction (SC) | Re: The amount of personal vehicles being used

Ok, ‘Number’ is the right diction and ‘not only… but also’ is appropriately used in C only. However, the worry is the incorrect use of ‘being’ as a modifier in all the five choices, giving a feeling that it could be ignored. It is certainly a bad usage and redundant. One can do very well dropping the word ‘being’.After all, this is from a reputed company.
