• A. Both assertion and reason are correct, and the reason is the correct explanation
• B. Both assertion and reason are correct, but the reason is not a correct explanation
• C. Assertion is correct, reason is incorrect.
• D. Both assertion and reason are incorrect.

Answer 1

The correct option is A Both assertion and reason are correct, and the reason is the correct explanation

The bones in the skull are joined by sutures or the synarthrodial joints. These joints are immovable in nature and are composed of fibrous tissue or fibrocartilage that imparts them the immovable character. There's no space between the skull bones. Except for mandible, all the sutures in the cranium are joined by these joints and are thus, immovable.

So, the correct answer is 'Both assertion and reason are correct, and the reason is the correct explanation'.
