Assertion (A) : Current flows from point A of the conductor to point B.

Reason (R) : Point A is at lower potential and point B is at higher potential.

Choose the correct option.

1. R is the correct explanation of A.
2. R is not the correct explanation of A.
3. If A is true, then R is false.
4. If A is false but R is false.

B, C

Current always flows from higher potential to lower potential. Thus, 

• R is not the correct explanation of A.
• If A is true, then R is false.
