Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Spongy bones contain bone marrow inside of them and are hence, the sites for erythrocyte formation. They also contain osteoclasts and osteoblasts. Hence, both the assertion and the reason are correct statements, but the reason is not the correct explanation for the assertion.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
