Answer 1

Answer: (A), (C)

It is easy to see that


is the general representation of cyclohexane.

But cyclohexane is also represented using newman projection to understand the stability using staggered and eclipsed configurations of the atoms.



If you look at this newman projection, you can easily see that it is in the staggered configuration. The axial and equatorial hydrogens are at the maximum possible distance from each other. This makes this configuration the most stable.
