Assertion (A) : The resistors are connected in parallel when resistance in a circuit is to be decreased. Reason (R) : On connecting the resistances in parallel, the potential difference across a resistor is proportional to its resistance.

Both (A) and (R) are true and (R) is the correct explanation of (A).   Both (A) and (R) are true but(R) is NOT the correct explanation of (A).   (A) is true but (R) is false.   Both (A) and (R) are false.

(A) is true but (R) is false.

On connecting the resistances in parallel, the potential difference across all resistors is the same.
