Which of the below given statements stands true?

Options

A. A person can contract AIDS due to unprotected sexual intercourse with an infected person.
B. A person can contract AIDS while getting permanent tattooing with an infected needle.
C. A person cannot contract AIDS by donating blood to a HIV infected person.
D. All of these

Explanation

To determine which statements about AIDS are true, let's analyze each option step by step.

### Step 1: Analyze the first statement.
**Statement**: A person can contract AIDS due to unprotected sexual intercourse with an infected person.

**Analysis**: This statement is true. AIDS (Acquired Immunodeficiency Syndrome) can be transmitted through unprotected sexual contact with someone who is HIV-positive (the virus that causes AIDS).

### Step 2: Analyze the second statement.
**Statement**: A person can contract AIDS while getting permanent tattooing with an infected needle.

**Analysis**: This statement is also true. If a needle used for tattooing is contaminated with HIV, it can transmit the virus to the person receiving the tattoo. Therefore, using unsterilized needles poses a risk of HIV transmission.

### Step 3: Analyze the third statement.
**Statement**: A person does not contract AIDS by donating blood to an HIV-infected person.

**Analysis**: This statement is misleading. While it is true that a healthy person donating blood to an HIV-infected person does not contract AIDS, the statement implies that the act of donating blood itself is safe from transmission. The risk lies in receiving blood from an infected person. Therefore, a person who donates blood does not get infected, but it is important to note that the donated blood must be screened to ensure safety.

### Step 4: Analyze the fourth statement.
**Statement**: All of these.

**Analysis**: Since the first two statements are true, and the third statement is somewhat misleading but can be interpreted as correct in the context provided, the overall conclusion is that all statements can be considered true in this context.

### Final Conclusion:
The correct answer is option 4: "All of these," as it encompasses the true statements regarding AIDS transmission.
