Chemistry · Structure of atom

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): Bohr's model of the hydrogen atom contradicts the Heisenberg uncertainty principle.\n Reason (R): Bohr model assumes well-defined circular orbits where both position and velocity can be known simultaneously and exactly. \nIn 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.
