Chemistry · Structure of atom

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Thomson's atomic model successfully explained the overall electrical neutrality of an atom. Reason (R): Thomson's model predicted the correct scattering distribution of alpha particles at large angles. 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.
