Read the following matches carefully
(i) Greater sciatic notch - Innominate bone
(ii) Obturator foramen - Innominate bone
(iii) Acromion process - Humerus
Which of these are correct?

Options

A. (i) and (ii)
B. (ii) and (iii)
C. (i) and (iii)
D. All are correct

Answer

To determine which of the matches are correct, we will analyze each pairing one by one.

### Step 1: Analyze the first match - Greater sciatic notch - Innominate bone
- The greater sciatic notch is a large notch located in the pelvis, specifically on the ilium, which is one of the components of the innominate bone (also known as the hip bone).
- Therefore, this match is **correct**.

### Step 2: Analyze the second match - Obturator foramen - Innominate bone
- The obturator foramen is a large opening formed by the ischium and pubis, which are also parts of the innominate bone.
- Thus, this match is also **correct**.

### Step 3: Analyze the third match - Acromion process - Humerus
- The acromion process is a bony projection on the scapula (shoulder blade), while the humerus is the long bone of the arm that runs from the shoulder to the elbow.
- Since the acromion is part of the scapula and not directly associated with the humerus, this match is **incorrect**.

### Conclusion
Based on the analysis:
- The correct matches are:
- (i) Greater sciatic notch - Innominate bone: **Correct**
- (ii) Obturator foramen - Innominate bone: **Correct**
- (iii) Acromion process - Humerus: **Incorrect**

Thus, the correct options are (i) and (ii).
