Concept: This question tests knowledge about the protective structures of the human brain, specifically the skull and the meninges.
Why (C) is correct:
- Statement I: The human brain is indeed well protected by the skull (cranium), which is a bony structure forming a protective case around it. This statement is correct.
- Statement II: The brain is covered by three protective membranes called meninges. From outer to inner, these are the dura mater, arachnoid mater, and pia mater. The arachnoid mater is the very thin, web-like middle layer. This statement is also correct.
Why other options are wrong:
- (A) Incorrect because Statement II is correct.
- (B) Incorrect because Statement I is correct.
- (D) Incorrect because both statements are correct.
NEET Tip: Remember the order of meninges from outside to inside as DAP (Dura, Arachnoid, Pia) or PAD (Pia, Arachnoid, Dura) if going from inside to outside.
Correct Answer: (C)
Both Statement I and Statement II are correct.
