★ Answer -
Both assertion and reasons are correct and reason is the correct explanation of assertion.⠀
Explanation :-
➛ The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area.
➛ Value of resistance of a conductor depends upon the nature, dimensions and the physical state of the conductor.
