Which of the following is correct about the heading of the Article 162 of Constitution of India ?

The official heading of Article 162 is 'Extent of executive power of State', and of the four options, D ('Extension of Executive Power of State') is the closest in meaning. Article 162 says the State's executive power extends to matters on which the State Legislature can make laws. The proviso limits it where the Union has executive power expressly conferred by the Constitution or by a Parliamentary law.

Why the others fail:

• A is the heading of Article 154, which vests executive power of the State in the Governor. It drops the idea of 'extent' altogether.
• B is the heading of Article 158, which covers conditions of the Governor's office, such as not being a member of a Legislature and not holding any office of profit.
• C is the heading of Article 156, which deals with the Governor's term of five years and tenure at the President's pleasure.

The concept links to the Union-State distribution of executive power, which mirrors Article 73 for the Union. This is a recurring Mains theme on Centre-State relations and cooperative federalism.

Trap: aspirants pick A because it sounds like the core idea. Article 154 is the Governor's executive power article, while Article 162 is about its extent.
