According to the World Health Organisation (WHO), reproductive health means a total well-being in all of the following aspects EXCEPT:

  1. Genetic
  2. Physical
  3. Behavioural and social
  4. Emotional

India initiated family planning programmes at a national level in the year:

  1. 2000
  2. 1971
  3. 1947
  4. 1951
Show answer and solution

Family planning programmes in India started in **1951** — India was among the first countries in the world to do so. 1971 is the year of MTP Act legalisation; do not confuse the two.

Amniocentesis has been legally banned in India for the purpose of:

  1. Determining the sex of the foetus
  2. Monitoring foetal lung maturity
  3. Detecting haemophilia in the foetus
  4. Detecting genetic disorders such as Down syndrome
Show answer and solution

Correct answer: A. Determining the sex of the foetus

Amniocentesis legitimately tests for genetic disorders (Down syndrome, haemophilia, sickle-cell anaemia). Its **misuse for sex-determination** — and the subsequent female-foeticide that follows — is what's statutorily banned in India.
