Read the following matches carefully
(i) Olecranon fossa - Ulna
(ii) Greater turberosity - Humerus
(iii) Foramen magnum - Skull
Which of these are correct?

Options

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

Answer

To solve the question, we need to evaluate each of the three matches provided:

1. **Olecranon fossa - Ulna**:
- The olecranon fossa is actually a depression found on the posterior side of the humerus, not the ulna. It accommodates the olecranon of the ulna when the arm is extended. Therefore, this match is **incorrect**.

2. **Greater tuberosity - Humerus**:
- The greater tuberosity is indeed a prominent area located at the top of the humerus. It serves as an attachment point for muscles of the shoulder. Thus, this match is **correct**.

3. **Foramen magnum - Skull**:
- The foramen magnum is a large oval opening located at the base of the skull, specifically in the occipital bone. This match is also **correct**.

Now, summarizing the correctness of each match:
- Olecranon fossa - Ulna: **Incorrect**
- Greater tuberosity - Humerus: **Correct**
- Foramen magnum - Skull: **Correct**

Thus, the correct matches are the second and third options.

**Final Answer**: The correct matches are (ii) Greater tuberosity - Humerus and (iii) Foramen magnum - Skull.
