The President can issue a proclamation of national emergency if he or she is satisfied that a grave emergency exists whereby the security of India or any part of the territory thereof is threatened, whether by war or external aggression or armed rebellion. The proclamation must be placed before each house of Parliament for approval within one month of its issue. If the proclamation is not approved by both houses of Parliament within one month, it shall cease to have effect.

Option B is incorrect because the President must place the proclamation before each house of Parliament for approval within one month, not two months.

Option C is incorrect because the President must place the proclamation before each house of Parliament for approval within one month, not four months.

Option D is incorrect because the President must place the proclamation before each house of Parliament for approval within one month, not six months.
