The question pertains to the Indian Constitution and how certain matters require a constitutional amendment with the ratification of legislatures of at least half of the States.

The answer options break down into four matters: The election of the President, the representation of States in the Parliament, any of the Lists in the 7th Schedule, and the abolition of the Legislative Council of a state.

Option 1 correctly identifies that the Election of the President, Representation of States in Parliament, and any of the Lists in the 7th Schedule fall under matters requiring a constitutional amendment with majority state ratification.

Option 2 incorrectly includes the abolition of the Legislative Council, which doesn`t require majority state ratification.

Option 3 and 4 also incorrectly list the abolition of the Legislative Council.

So by rule of thumb, only the election of the President, representation of States in Parliament, and amendments to the 7th schedule require a constitutional amendment with the ratification of not less than half of the State Legislatures, making option 1 the correct answer.
