The potential energy is relative quantity, it depends on reference position, while comparing potential energy in two positions, consider negative sign.
, if r is decreased, U is increased.
, if r is decreased, U is decreased.
, if r is increased, U is increased.
, if r is decreased, U is increased.

So option is wrong.
