Find the odd one out from the following .

Options

A. Humerus , thigh , tibia and fibula, radius and ulna
B. Metacarpals and metatarsals , phalanges of fingers and toes
C. Scapula of shoulder bone , sternum , cranial bones , vertebrae
D. Carpals of wrist and tarsals of ankle

Answer

To solve the question "Find the odd one out from the following," we will analyze each option provided and determine which one does not belong with the others based on their anatomical classification.

### Step-by-Step Solution:

1. **Identify the Options:**
- Option 1: Humerus, thigh, tibia and fibula, radius and ulna
- Option 2: Metacarpals and metatarsals, phalanges of fingers and toes
- Option 3: Scapula of Shoulder Bone, Sternum, Cranial Bones, Vertebrae
- Option 4: Couples of wrists and tarsals of ankles

2. **Analyze Option 1:**
- Humerus, tibia, fibula, radius, and ulna are all long bones found in the limbs (humerus in the arm, tibia and fibula in the leg, radius and ulna in the forearm).
- Conclusion: This option consists of long bones from the appendicular skeleton.

3. **Analyze Option 2:**
- Metacarpals and metatarsals are the bones of the hands and feet, respectively, while phalanges are the finger and toe bones.
- Conclusion: This option consists of bones that are part of the appendicular skeleton.

4. **Analyze Option 3:**
- Scapula (shoulder bone) is part of the appendicular skeleton, while the sternum, cranial bones, and vertebrae are part of the axial skeleton.
- Conclusion: This option contains a mix of bones from different skeletons (appendicular and axial).

5. **Analyze Option 4:**
- Couples of wrists (carpals) and tarsals of ankles are also part of the appendicular skeleton.
- Conclusion: This option consists of bones from the appendicular skeleton.

6. **Determine the Odd One Out:**
- After analyzing all options, Option 3 (Scapula, Sternum, Cranial Bones, Vertebrae) is the odd one out because it contains bones from both the appendicular skeleton (scapula) and the axial skeleton (sternum, cranial bones, vertebrae), while the other options consist solely of bones from the appendicular skeleton.

### Final Answer:
The odd one out is **Option 3: Scapula of Shoulder Bone, Sternum, Cranial Bones, Vertebrae**.
