The phenomenon of sperm activation in mammals is known as capacitation. It takes about

Options

A. 1hr
B. 5-6 hrs
C. 24 hrs
D. 10-12 hrs

Answer

**Step-by-Step Solution:**

1. **Understanding Capacitation**: Capacitation is the process that sperm undergo to gain the ability to fertilize an egg. It involves various physiological changes that prepare the sperm for the fertilization process.

2. **Duration of Capacitation**: The question asks about the time it takes for capacitation to occur in mammals.

3. **Reviewing Options**: The options provided are:
- 1 hour
- 5 to 6 hours
- 24 hours
- 10 to 12 hours

4. **Identifying Correct Duration**: Capacitation typically occurs after ejaculation and involves changes such as alterations in the sperm's membrane and motility. Based on biological studies, capacitation takes about 10 to 12 hours.

5. **Conclusion**: Therefore, the correct answer to the question is **10 to 12 hours**.
