B. Centromere
C. Centrosome
D. Golgi body

Answer

To answer the question "Which structure is present in Chromosomes?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a specific structure that is present in chromosomes. We need to analyze the options provided to identify the correct structure.

2. **Evaluate the Options**:
- **Option 1: Nucleus**: The nucleus is not a structure found within chromosomes; rather, it is the organelle that contains the chromosomes. Therefore, this option is incorrect.
- **Option 2: Centromere**: The centromere is a specific region of a chromosome that links sister chromatids together. It is indeed a structure present in chromosomes, making this option correct.
- **Option 3: Centrosome**: The centrosome is an organelle that plays a role in cell division but is not a part of the chromosome itself. Hence, this option is incorrect.
- **Option 4: Golgi Body**: The Golgi body is involved in protein packaging and secretion and is not related to the structure of chromosomes. Therefore, this option is also incorrect.

3. **Conclusion**: After evaluating all the options, the only structure that is present in chromosomes is the **centromere**.

### Final Answer:
The correct structure present in chromosomes is the **Centromere**.
