The most effective method of contraception is

Options

A. Multiple ovulation embryo transfer
B. Tubal ligation
C. Rhythm method
D. Lactational amenorrhea

Answer

To determine the most effective method of contraception from the given options, we can analyze each method:

1. **Multiple Ovulation Embryo Transfer (MOET)**: This is a technique used primarily in animal breeding, where multiple embryos are transferred to increase the chances of pregnancy. It is not a method of contraception but rather a method to enhance fertility.

2. **Tubal Ligation**: This is a surgical procedure that involves cutting and tying the fallopian tubes in females. This method prevents the sperm from reaching the egg, thus preventing fertilization. It is considered a permanent form of contraception and is highly effective.

3. **Rhythm Method**: This is a natural family planning method where couples avoid intercourse during the fertile window of the menstrual cycle. While it can be effective if done correctly, it is less reliable than surgical methods because it requires precise tracking of the menstrual cycle and can be affected by irregular cycles.

4. **Lactational Amenorrhea**: This is a natural method of contraception that relies on the absence of menstruation during breastfeeding. It can be effective for up to six months postpartum, but its reliability decreases as the baby starts to consume other foods and breastfeeding frequency changes.

After analyzing these options, it is clear that:

- **Tubal Ligation** is the most effective method of contraception among the choices provided because it is a permanent solution that prevents fertilization entirely.

**Final Answer**: The most effective method of contraception is **B. Tubal Ligation**.
