Assertion (A): Zinc fails to display the characteristic features of transition metals. Reason (R): In zinc the outermost (d) shell is fully occupied. Choose the correct option.

1. (A) if both (A) and (R) are true and (R) is the correct explanation of (A)
2. (B) if both (A) and (R) are true but (R) is not correct explanation of (A)
3. (C) if (A) is true but (R) is false
4. (D) if (A) is false and (R) is true

Correct answer: (A) if both (A) and (R) are true and (R) is the correct explanation of (A)

Solution

Zinc has a completely filled 3d subshell (3d¹⁰), so it has no partially filled d-orbitals; this is exactly why it lacks the typical transition-metal characteristics, making R the correct explanation of A.
