Given below are two statements: one is labelled as Assertion A and the other is labelled as
Reason R.
Assertion A: The Bohr model is applicable to hydrogen and hydrogen-like atoms only.
Reason R : The formulation of Bohr model does not include repulsive force between electrons.
In the light of the above statements, choose the correct answer from the options given below :

Options

  1. ABoth A\mathrm{A} and R\mathrm{R} are true but R\mathrm{R} is NOT the correct explanation of A\mathrm{A}.
  2. BA\mathrm{A} is false but R\mathrm{R} is true.
  3. CBoth A\mathrm{A} and R\mathrm{R} are true and R\mathrm{R} is the correct explanation of A\mathrm{A}.
  4. DA\mathrm{A} is true but R\mathrm{R} is false.

Correct answer

C. Both A\mathrm{A} and R\mathrm{R} are true and R\mathrm{R} is the correct explanation of A\mathrm{A}.
