Solution

The correct option is C Assertion is correct but Reason is incorrect
The 8th, 9th, and 10th pairs of ribs do not articulate directly with the sternum but join the seventh rib with the help of hyaline cartilage. These are called vertebrochondral (false) ribs.

So the correct option is" Assertion is correct but the reason is incorrect".
