Question

Accepted Answer

Vitamin B_3 is also called Niacin, which is why Option 3 is the correct answer. Niacin is an essential nutrient that plays a crucial role in the body. It is involved in the metabolism of carbohydrates, fats, and proteins, helping to convert food into energy. Niacin is also important for maintaining healthy skin, nerves, and digestion. Additionally, it has been shown to help lower cholesterol levels and improve heart health.

Now, let's explain why the other options are incorrect:

1. **Biotin**: Biotin is actually Vitamin B_7, not Vitamin B_3. It is important for the health of hair, skin, and nails, and it also plays a role in the metabolism of fats and carbohydrates. However, it is not the same as Niacin.

2. **Folic acid**: Folic acid is another B vitamin, specifically Vitamin B_9. It is crucial for DNA synthesis and repair, and it is especially important during periods of rapid growth, such as pregnancy and fetal development. Folic acid is not the same as Niacin.

3. **Thiamine**: Thiamine is known as Vitamin B_1. It is essential for glucose metabolism and plays a key role in nerve, muscle, and heart function. Thiamine is distinct from Niacin and serves different functions in the body.

In summary, Niacin is the correct name for Vitamin B_3, which is why Option 3 is the correct answer. The other options refer to different B vitamins with different roles and functions in the body.
