B. Sterilisation - Inhibit gamete formation
C. IUDSs - Inhibit implantation
D. Natural methods - Avoid chances of ovum and sperm meeting.

Answer

To determine which of the following is a wrong match between the type of contraception and its function, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Option A: Contraceptive Pills Inhibit Ovulation**
- Contraceptive pills are hormonal medications that prevent ovulation. They work by providing hormones that regulate the menstrual cycle and inhibit the release of eggs from the ovaries.
- **Conclusion:** This is a correct match.

2. **Option B: Sterilization Inhibits Gamete Formation**
- Sterilization is a surgical method used to prevent pregnancy. In males, it is known as vasectomy, and in females, it is called tubal ligation. These procedures block the transport of gametes (sperm or eggs) but do not stop their production.
- **Conclusion:** This is a wrong match because sterilization does not inhibit gamete formation; it only prevents the transport of gametes.

3. **Option C: IUDs Inhibit Implantation**
- Intrauterine devices (IUDs) are contraceptive devices placed in the uterus. They can prevent pregnancy by inhibiting implantation of a fertilized egg and making the uterine environment unsuitable for implantation.
- **Conclusion:** This is a correct match.

4. **Option D: Natural Methods Avoid Chances of Ovum and Sperm Meeting**
- Natural contraceptive methods, such as periodic abstinence and lactational amenorrhea, involve avoiding sexual intercourse during the fertile period to prevent the meeting of sperm and ovum.
- **Conclusion:** This is a correct match.

### Final Answer:
The wrong match between the type of contraception and its function is **Option B: Sterilization inhibits gamete formation**.
