Present in nucleus is :

Options

A. Golgi complex
B. Lysosome
C. Mitochondria
D. Chromosome

Answer

To answer the question "Present in nucleus is:", we will analyze the options provided and determine which one is found in the nucleus.

### Step-by-Step Solution:

1. **Understanding the Nucleus**:
- The nucleus is a vital organelle in eukaryotic cells. It is enclosed by a nuclear membrane and contains the cell's genetic material.

2. **Analyzing the Options**:
- **Option 1: Golgi Complex**:
- The Golgi complex is not found in the nucleus; it is located in the cytoplasm. Its primary function is to modify, sort, and package proteins and lipids for secretion or delivery to other organelles.
- **Option 2: Lysosomes**:
- Lysosomes are also located in the cytoplasm, not in the nucleus. They contain digestive enzymes that help in breaking down waste materials and cellular debris.
- **Option 3: Mitochondria**:
- Mitochondria, known as the powerhouse of the cell, are found in the cytoplasm and are responsible for producing energy through cellular respiration.
- **Option 4: Chromosome**:
- Chromosomes are structures within the nucleus that contain DNA. They carry genetic information and are crucial for cell division and inheritance.

3. **Conclusion**:
- After evaluating all the options, the only structure that is present in the nucleus is **Chromosome**. Therefore, the correct answer is **Option 4: Chromosome**.

### Final Answer:
**Present in nucleus is: Chromosome (Option 4)**.
