The Constitution of India clearly divides the functions of the Union Government into three parts — the Legislature, the Executive, and the Judiciary.
According to Article 53 of the Constitution:
“The executive power of the Union shall be vested in the President and shall be exercised by him either directly or through officers subordinate to him.”
Step 1: Understand the term "Executive"
- The Executive is responsible for the implementation of laws and the administration of the country.
Step 2: Constitutional vs. Real Head
- The President is the nominal or constitutional head of the Executive, meaning he performs ceremonial duties.
- The Prime Minister is the real executive authority who advises the President and leads the Cabinet.
Step 3: Analyze other options
- Option (A): Prime Minister is the real head, not the constitutional head.
- Option (B): Speaker of Lok Sabha is part of the Legislature, not the Executive.
- Option (D): Chief of Army is under the Ministry of Defence, not the constitutional head.
Hence, the correct answer is (C) President.
