Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Agarose is a polysaccharide obtained from red algae. Agarose dissolves in hot water and when it is cooled, it forms a gel. Pore size depends upon agarose concentration. In general, a 1% (w/v) gel will have a pore size of 150 nm while a 0.16% gel has a pore size of 500 nm.
So, the correct option is 'Option A'.
