Answer 1

The correct option is B Dura mater

• The membrane which covers the brain and the spinal cord is called as the meninges.
• There are three layers of the meninges. The outermost is the Dura mater, middle one is the arachnoid mater and the innermost is the pia mater.
• Dura mater is the tough membrane which is present in the outermost region. The three meninges provide protection to the brain from shock and injury.
• Thus, the correct answer is option B.
