Answer

To determine the full proof method of contraception from the given options, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understand the Options**:
The options provided are:
- A) Implants
- B) Lactational Amenorrhea
- C) Condoms
- D) Sterilization

2. **Evaluate Option A - Implants**:
- Implants are a form of long-term contraception that can be effective for about 5 years.
- While they are effective, they are not considered foolproof as there is still a small chance of failure.
- **Conclusion**: Not a full proof method.

3. **Evaluate Option B - Lactational Amenorrhea**:
- This method relies on breastfeeding to suppress ovulation and is effective for about 6 months postpartum.
- Although it can be effective during this period, it does not guarantee contraception after 6 months or if breastfeeding is not exclusive.
- **Conclusion**: Not a full proof method.

4. **Evaluate Option C - Condoms**:
- Condoms are a barrier method of contraception.
- They are effective but can fail due to breakage or improper use, allowing sperm to reach the egg.
- **Conclusion**: Not a full proof method.

5. **Evaluate Option D - Sterilization**:
- Sterilization involves surgical procedures such as vasectomy for males and tubal ligation for females.
- These methods are designed to permanently prevent the transfer of sperm and eggs, making them highly effective with very little chance of failure.
- **Conclusion**: This is considered a foolproof method of contraception.

6. **Final Answer**:
- Based on the evaluations, the full proof method of contraception among the options is **D) Sterilization**.
