Solution

The correct option is C Assertion is correct but Reason is incorrect
Assertion is correct as lipids present on the outer and inner side of the bilayer are commonly different, for example lecithin on the outer side and cephalin on the inner side of erythrocyte membrane.
Reason is false as oligosaccharides are attached to external surface of lipids and proteins of a biomembrane. They are absent on the inner side.
So, the correct answer is option C.
