Option 1 -> Includes weight which is not a factor in resistance, and excludes the nature of material which is essential.
Option 2 -> Includes weight which is not a factor, and excludes area of cross-section which is crucial.
Option 3 -> Correctly includes length, area of cross-section, and nature of material - all three factors in the resistance formula R = ρL/A.
Option 4 -> Incorrectly includes weight and excludes length, which is a fundamental factor.
Hence, Option 3: (A), (C) and (D) only -> The resistance of a conductor follows R = ρL/A, where ρ is resistivity (depends on material nature), L is length, and A is area of cross-section. Weight is not a determining factor as resistance depends on geometry and material properties, not mass -> correct
