$V=Ed$
$ΔU=ΔV Q$

The Attempt at a Solution

Since the electric field is constant between charged plate conductors , d and the potential difference (ΔV) don't change.So, the potential energy (ΔU) remain the same .
The answer is (C). Right ?

Sounds good to me. The change in potential and potential energy is the same for all paths.

The answer is (C). Right ?

How did you deduce this from the above?
