Explanation:

- Option 1: Governor of the State

- The Governor does not decide the number of judges. They act as the constitutional head of the state.

- Option 2: Parliament

- Parliament has the power to organize the jurisdiction and powers of the High Court, but it doesn't directly determine the number of judges.

- Option 3: President

- The President of India determines the number of judges in a High Court as per the constitution, in consultation with the Chief Justice of India and the Governor of the state.

-

- Option 4: State Government

- The State Government has no role in deciding the number of judges. Its functions are more administrative.

Thus, the President, with appropriate consultations, decides the number of judges in a High Court.
