Solution

The correct options are
B Potential difference between two points.
C Change in potential energy of a two charge system.
$δ V = V_{A} - V_{B}$
$= (V_{A} + V_{r e f}) - (V_{B} + V_{r e f}) = V_{A} - V_{B}$
i.e., does not depend on reference. Similarly, $δ U$ also independent of $U_{r e f}$ .
