Answer

To determine which statement is true regarding vitamins, let's analyze the options step by step.

### Step 1: Understand the Requirement of Vitamins
Vitamins are essential nutrients that the body needs in small amounts to function properly. They do not need to be consumed in large quantities.

**Hint:** Remember that vitamins are required in micrograms or milligrams, not grams.

### Step 2: Evaluate the Statements
1. **Vitamins are needed in large amounts to maintain good health.**
- This statement is false. Vitamins are required in small amounts.

2. **Vitamins are secreted by ductless glands.**
- This statement is also false. Vitamins are not secreted by glands; they are obtained from the diet.

3. **Vitamins A, D, E, K are fat-soluble, while B complex and C are water-soluble.**
- This statement is true. Vitamins A, D, E, and K are indeed fat-soluble, while the B complex vitamins and vitamin C are water-soluble.

4. **All vitamins are synthesized in the human body.**
- This statement is false. While some vitamins can be synthesized in the body (like vitamin D), others must be obtained from the diet.

### Step 3: Identify the True Statement
From the analysis above, the only true statement is that vitamins A, D, E, and K are fat-soluble, while the B complex and vitamin C are water-soluble.

### Conclusion
The correct answer to the question is:
**Vitamins A, D, E, and K are fat-soluble, while B complex and C are water-soluble.**

### Final Answer
The true statement regarding vitamins is: **Vitamins A, D, E, and K are fat-soluble, while B complex and C are water-soluble.**
