Read the passage given below and answer the following questions.

The Ministers are individually responsible to the President, i.e., they hold office during the pleasure of the President and may be dismissed by him on the advice of the Prime Minister. The principle of individual responsibility to the head of the state is embodied in Art. 75 (2) — "The Ministers shall hold office during the pleasure of the President." Though the ministers are collectively responsible to the Legislature, they shall be individually responsible to the President and shall be liable to be dismissal even when they have the confidence of the House of people. But since the Prime Minister's advice will be available in the matter of dismissing other Ministers individually, it may be expected that this power of the President will virtually be a power of the Prime Minister against his colleagues. Thus, in effect, a minister is individually responsible to the Prime Minister.
