Solution

Both A and R are true but R is not the correct explanation of A.

Explanation:

Assertion A is true because electrical conduction in metals and alloys occurs through mobile electrons. Reason R is also true as a complementary general fact, but it states only the case of non-metals and does not directly establish the mechanism of conduction in metals and alloys. Hence, R is not the correct explanation of A.
