Sentence Correction (SC) | Re: In 1984 medical researchers at Harvard and Stanford

Hi Akhil,

The verb -ing modifier is incorrect in option A. Since it should refer to the previous clause, it is illogically referring to sedentary lifestyles. It is not the lifestyles that are recommending something, but the researchers.

I hope this helps to clarify your doubt!
