C. 4 - 12 weeks
D. 20 years

Answer

### Step-by-Step Solution:

1. **Understanding Syphilis**:
- Syphilis is a sexually transmitted disease (STD) caused by the bacterium *Treponema pallidum*.

2. **Stages of Syphilis**:
- Syphilis progresses through three main stages:
- **Primary Stage**: Characterized by a painless ulcer (called a chancre) at the site of infection, typically on the genitals. This stage marks the initial infection.
- **Secondary Stage**: The chancre heals, but other symptoms appear, such as skin rashes, hair loss, and swollen lymph nodes.
- **Tertiary Stage**: Chronic ulcers may reappear, and severe complications can occur, including paralysis and brain damage.

3. **Latent Period**:
- After the secondary stage, there is a "latent" or symptomless period where the disease is not active and symptoms are not present. This period can last for a significant duration.

4. **Duration of the Latent Period**:
- The latent period can vary widely, typically lasting from 12 months up to 20 years. The correct answer to the question regarding the duration of the symptomless period in syphilis is **20 years**.

5. **Conclusion**:
- Therefore, the "symptomless" or latent period in the case of syphilis may last for up to **20 years**.
