GMAT Critical Reasoning (CR) | Re: Images from ground-based telescopes are invariably distorted by the

HiAjiteshArun ,

Is C wrong because it attacks the premise rather than conclusion ?
C says by a good choice of ground location, large aperture telescopes(LA) can avoid most types of image distorting things.
This attacks the given premise that ground based telescopes' images are distorted. The premise covers all ground based telescopes.
In this option we can assume that LA telescopes are ground based.

Am I thinking right ?

Thanks,
