B. Only statement B is correct.
C. Both statement A and B are correct.
D. Both statement A and B are incorrect.

Answer

To solve the question regarding the statements about the human skull and ribs, let's analyze each statement step by step.

### Step 1: Analyze Statement A
- **Statement A**: "The human skull is monocondylic."
- A monocondylic skull has a single occipital condyle. This type of skull is typically found in reptiles.
- In humans, the skull is actually **dichondylic**, meaning it has **two occipital condyles**. Therefore, Statement A is **incorrect**.

### Step 2: Analyze Statement B
- **Statement B**: "Ribs in humans are bicephalic."
- Bicephalic means having two heads or two articulation surfaces. In the case of human ribs, they have two articulation points on the dorsal side (one for the vertebra and one for the sternum).
- Thus, Statement B is **correct**.

### Step 3: Conclusion
- Since Statement A is incorrect and Statement B is correct, we can conclude:
- **Only Statement B is correct.**

### Final Answer
The correct answer is: **Only Statement B is correct.**
