Answer

To solve the question regarding the correct statement about conception and pregnancy, we need to understand the definitions and timelines of these two processes.

### Step-by-Step Solution:

1. **Understanding Conception**:
- Conception occurs when fertilization takes place, which is the moment when the sperm from the male fuses with the egg from the female. This results in the formation of a zygote.
- Therefore, we can say that a woman conceives on the day of fertilization.

2. **Understanding Pregnancy**:
- Pregnancy is defined as the condition that begins when the fertilized egg (zygote) successfully implants itself into the uterine wall.
- This implantation typically occurs about a week after fertilization.

3. **Analyzing the Options**:
- **Option 1**: "A woman conceives as well as becomes pregnant on the day of fertilization."
- This is incorrect because while conception occurs on the day of fertilization, pregnancy does not occur until implantation, which is about a week later.

- **Option 2**: "A woman conceives as well as becomes pregnant about a week after fertilization."
- This is also incorrect because conception occurs on the day of fertilization, not a week later.

- **Option 3**: "A woman conceives on the day of fertilization while she becomes pregnant a week after fertilization."
- This is correct. It accurately states that conception happens on the day of fertilization and pregnancy occurs about a week later.

- **Option 4**: "A woman becomes pregnant on the day of fertilization while she conceives a week after fertilization."
- This is incorrect because it reverses the definitions; conception occurs first, followed by pregnancy.

4. **Conclusion**:
- The correct statement is **Option 3**: "A woman conceives on the day of fertilization while she becomes pregnant a week after fertilization."
