detailed solution

Correct option is D

Charge flows from high potential to lower potential. If positive charge is given, then V1 < V2 as r1 > r2So positive charge flows from Q ➔ P.If negative charge is given, then V1 > V2So negative charge flows form P ➔ Q.Since it is not given that whether the charge given is positive or negative, hence the information is incomplete.
