Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Some carrier proteins allow transport only if two types of molecules move together. This is called cotransport. Symport and antiport are two types of cotransport. Symport allows both the molecules to move in same direction and antiport allows both the molecules to move in opposite direction.
