Bone forming cells are

Options

A. osteoblasts
B. osteoclasts
C. chondroclasts
D. chondroblasts

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the type of cells responsible for forming bone.

2. **Identifying the Options**: The options provided are:
- A) Osteoblast
- B) Osteoclast
- C) Chondroclast
- D) Chondroblast

3. **Analyzing Each Option**:
- **Osteoblast**: These are the cells that produce new bone material. They are specifically involved in the formation of bone tissue.
- **Osteoclast**: These cells are responsible for the dissolution and absorption of bone. They break down bone tissue, which is the opposite of forming it.
- **Chondroclast**: These are multinucleated cells that are involved in the absorption of calcified cartilage, not bone.
- **Chondroblast**: These cells originate from mesenchymal stem cells and are responsible for forming cartilage, not bone.

4. **Conclusion**: Based on the analysis, the only cells that are responsible for forming bone are the osteoblasts.

5. **Final Answer**: Therefore, the correct answer is **A) Osteoblast**.
