Which one is a natural method of family planning?

Correct option is D

Sol. Natural family planning methods rely on tracking fertility signals without the use of hormones or devices. Basal Body Temperature (BBT) and cervical mucus monitoring are two key methods to detect ovulation and avoid unprotected sex during fertile days, helping in pregnancy prevention.
Explanation of each option:
· (a) BBT – This method involves tracking daily temperature changes; a slight rise indicates ovulation. It requires consistent and accurate morning readings.
· (b) Cervical mucus – This method identifies fertility based on texture and stretchiness of vaginal mucus, which becomes clear and slippery during ovulation.
· (c) MTP and mucus – MTP is not a preventive method; it is used after conception and not part of family planning techniques.
· (d) Both (a) and (b) – Correct. These are established natural methods and are often used in combination for better accuracy.
