Options

  1. A(A) is true, (R) is true and (R) is the correct explanation for (A)
  2. B(A) is true, (R) is true but (R) is not the correct explanation for (A)
  3. C(A) is true but (R) is false
  4. D(A) is false but (R) is true

Correct answer

A. (A) is true, (R) is true and (R) is the correct explanation for (A)

Step-by-step solution

Mo has the highest exchange energy as it gains the half-filled d-orbital configuration.
