A) Arachnoid-piamater-duramater
B) Arachnoid-duramater-piamater
C) Piamater-arachnoid-duramater
D) Duramater-arachnoid-piamater
Correct Answer: D

Arachnoid is thin, but non-vascular and abundant collagen and elastin fibres, separated from piamater. Piamater is also thin, soft, highly vascular and closely adhered to brain surface.
