Find the odd one out .

Options

A. Ilium, ischium, and pubis
B. Deltoid rige, olecranon process, trochanter
C. Suprascapula, coracoid, scapula, trochlea
D. Epiphysis, xiphisternum, olecranon notch

Answer

To solve the question "Find the odd one out," we need to analyze the given options and identify which one does not belong with the others based on their anatomical classification or function.

### Step-by-Step Solution:

1. **Identify the Options:**
- Option A: Ileum, Ischium, Pubis
- Option B: Deltoid Ridge, Olecranon Process, Trochanter
- Option C: Suprascapula, Coracoid Scapula, Trochlea
- Option D: Epiphysis, Xiphoid Process, Olecranon Notch

2. **Analyze Each Option:**
- **Option A (Ileum, Ischium, Pubis):** These are all bones that form the pelvic girdle. They are part of the lower limb structure.
- **Option B (Deltoid Ridge, Olecranon Process, Trochanter):** These are features associated with the forelimb (upper limb) bones. The deltoid ridge is on the humerus, the olecranon process is part of the ulna, and the trochanter is a feature of the femur.
- **Option C (Suprascapula, Coracoid Scapula, Trochlea):** These are also associated with the forelimb. The suprascapula and coracoid are parts of the scapula, and the trochlea is a part of the humerus.
- **Option D (Epiphysis, Xiphoid Process, Olecranon Notch):** The epiphysis is the end part of a long bone, the xiphoid process is part of the sternum, and the olecranon notch is part of the ulna.

3. **Determine the Odd One Out:**
- **Option A** (Ileum, Ischium, Pubis) is the odd one out because it consists of bones that form the pelvic girdle, while all the other options (B, C, D) comprise structures associated with the forelimb or upper body.

### Conclusion:
The odd one out is **Option A: Ileum, Ischium, Pubis**.
