Bone forming cells among these is

Options

A. Osteoclast
B. Osteoblast
C. Chondroblast
D. Chndroclast

Answer

**Step-by-Step Solution:**

1. **Understanding Bone Forming Cells**: The question asks for the identification of bone-forming cells. These cells are responsible for the creation and maintenance of bone tissue.

2. **Analyzing the Options**:
- **Option 1: Osteoclast**: This term is derived from "osteo" meaning bone and "clast" meaning to break. Osteoclasts are cells that break down bone tissue, which means they do not form bone but rather resorb it. Therefore, they cannot be the answer.

- **Option 2: Osteoblast**: This term also comes from "osteo" meaning bone, but "blast" refers to building or forming. Osteoblasts are the cells responsible for the formation of new bone. They produce osteoids, which are the organic components of the bone matrix. Thus, they are indeed bone-forming cells.

- **Option 3: Chondroblast**: Chondroblasts are cells that form cartilage, not bone. They produce chondrocytes, which are the cells found in cartilage. Since the question specifically asks for bone-forming cells, this option is not relevant.

- **Option 4: Chondroclast**: Similar to osteoclasts, chondroclasts break down cartilage. They are not involved in the formation of bone, making this option incorrect as well.

3. **Conclusion**: Based on the analysis of the options, the correct answer is **Option 2: Osteoblast**, as these are the cells that form new bone.
