Explanation:

To answer this, we must identify which President also served as the inaugural Chief Minister of a state. - **Option A (Dr. B. D. Jatti):** Dr. B. D. Jatti served as the Chief Minister of Mysore State (now Karnataka) from $1958$ to $1962$. He later became the fifth Vice President of India and acting President. While he was a Chief Minister and later President, he was not the *first* Chief Minister of a state among the options in the context of state formation or reorganization. - **Option B (Dr. Shankar Dayal Sharma):** Dr. Shankar Dayal Sharma was the Chief Minister of Bhopal State from $1952$ to $1956$. Bhopal was a Part 'C' state that later merged into Madhya Pradesh. He later became the ninth President of India. While he was a Chief Minister, the question often implies a major state post-reorganization. - **Option C (Dr. Rajendra Prasad):** Dr. Rajendra Prasad was the first President of India, serving from $1950$ to $1962$. He was a prominent leader in the Indian independence movement but never held the position of Chief Minister of any state. Thus, this option is incorrect. - **Option D (Neelam Sanjeeva Reddy):** Neelam Sanjeeva Reddy served as the first Chief Minister of the reorganized Andhra Pradesh state from $1956$ to $1960$, and again from $1962$ to $1964$. He later became the sixth President of India from $1977$ to $1982$. Given his role as the first Chief Minister of the linguistically reorganized state of Andhra Pradesh, he is the most appropriate answer to the question regarding a President who was the 'first Chief Minister of a State in India'.
