Options

A. A person may contact syphilis by sharing milk with one already suffering from the disease
B. Haemophilia is one of the STIs
C. Genital herpes and sickle-cell anamia are both STIs
D. None of these

Explanation

To determine which statement is correct regarding sexually transmitted infections (STIs), we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "A person may contact syphilis by sharing milk with one already suffering from the disease."
- **Explanation:** Syphilis is a sexually transmitted infection caused by bacteria. It is primarily transmitted through sexual contact, not through casual contact such as sharing food or drinks. Therefore, this statement is **incorrect**.

2. **Analyze the Second Statement:**
- **Statement:** "Hemophilia is one of the STIs."
- **Explanation:** Hemophilia is a genetic disorder that affects blood clotting and is inherited from parents. It is not transmitted through sexual contact, so this statement is also **incorrect**.

3. **Analyze the Third Statement:**
- **Statement:** "Genital herpes and sickle cell anemia are both STIs."
- **Explanation:** Genital herpes is indeed a sexually transmitted infection caused by the herpes simplex virus. However, sickle cell anemia is a genetic disorder characterized by abnormal hemoglobin in red blood cells, and it is not an STI. Therefore, this statement is **incorrect** as well.

4. **Analyze the Fourth Statement:**
- **Statement:** "None of these."
- **Explanation:** Since all the previous statements have been shown to be incorrect, this statement is the only correct option. Therefore, the answer is **option D: None of these**.

### Final Answer:
The correct answer is **D: None of these**.
