D. d) iv,iii,I,iii

Answer

To solve the question of matching the columns regarding the number of certain bones in the human body, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Bones in Column A:**
- The bones listed in Column A are:
- Ribs
- Vertebrae
- Phalanges
- Sternum

2. **Determine the Number of Each Bone:**
- **Ribs:**
- There are 12 pairs of ribs. Since each pair consists of 2 ribs, the total number of ribs is 12 x 2 = 24.
- **Vertebrae:**
- The human spine consists of 26 vertebrae, which includes cervical (7), thoracic (12), lumbar (5), sacrum (5, fused), and coccyx (4, fused).
- **Phalanges:**
- The phalanges are the bones of the fingers. There are 14 phalanges in total (3 for each finger and 2 for each thumb).
- **Sternum:**
- The sternum is a single flat bone located in the center of the chest, and there is only 1 sternum.

3. **Match Each Bone with Its Number:**
- Ribs → 24 (iv)
- Vertebrae → 26 (i)
- Phalanges → 14 (ii)
- Sternum → 1 (iii)

4. **Write the Final Matches:**
- a) Ribs → (iv) 24
- b) Vertebrae → (i) 26
- c) Phalanges → (ii) 14
- d) Sternum → (iii) 1

### Final Answer:
The correct matches are:
- a → iv (Ribs → 24)
- b → i (Vertebrae → 26)
- c → ii (Phalanges → 14)
- d → iii (Sternum → 1)

Thus, the final answer is:
**C. a → iv, b → i, c → ii, d → iii**
