Physics · Electrostatic Potential

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Work done by an external force in bringing a test charge from infinity to a point in an electric field is path-independent. Reason (R): Electrostatic force is conservative, hence the line integral of electric field around any closed path is zero. In the light of the above statements, choose the correct answer from the options given below:

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