Which of the following can be included under natural methods of birth control ?

Options

A. Rhythm method
B. Coitus interruptus
C. Lactational amenorrhea
D. All of these

Answer

To answer the question "Which of the following can be included under natural methods of birth control?" we will analyze each option provided:

1. **Rhythmic Period**: This method involves tracking the menstrual cycle to determine fertile and infertile days. Couples can avoid intercourse during the fertile period to prevent pregnancy. This method requires education and awareness of the woman's cycle.

2. **Coitus Interruptus**: Also known as the withdrawal method, this involves the male partner withdrawing before ejaculation to prevent sperm from entering the female reproductive tract. While this method requires self-control and timing, it is considered a natural method of birth control.

3. **Lactational Amenorrhea**: This method relies on the natural infertility that occurs when a woman is exclusively breastfeeding. During this period, which typically lasts for about six months postpartum, ovulation is suppressed, reducing the chances of conception.

4. **All of the Above**: Since all three methods mentioned (Rhythmic Period, Coitus Interruptus, and Lactational Amenorrhea) are recognized as natural methods of birth control, this option is correct.

### Final Answer:
The correct answer is **All of the Above**.
