Step 1: Group the set.
Options (A), (B), (C) are all Presidents of India. Dr. Rajendra Prasad (1st), Dr. S. Radhakrishnan (2nd), Dr. Zakir Husain (3rd).
Step 2: Identify the odd one out.
Pt. Jawaharlal Nehru was the first Prime Minister, not a President—hence mismatched.
Step 3: Conclude.
\[
\boxed{\text{Pt. Jawaharlal Nehru (Option D) is the odd one out.}}
