Which option gives the correct purpose of family planning?

Correct answer: Responsibly understanding family size and births

The direct answer is A: family planning helps people make responsible, informed decisions about family size and births. Its purpose is connected with planning the timing and spacing of children, considering the health and well-being of family members, and using reliable information and voluntary choices. Option A is correct because it describes decision-making about births and family size without force. Option B is wrong because family planning is not intended to increase deaths; it is associated with health, care and responsible choices. Option C is wrong because migration is the movement of people from one place to another and is not the purpose of family planning. Option D is wrong because family planning cannot increase the physical area of a place. The key distinction is that family planning concerns births and family well-being, not death rates, migration control or land area. A useful memory cue is: family planning means planning the family, not controlling geography or movement.
