Which of the following statements are correct?

(A) Resistance is a property that resists the flow of electrons in a conductor.

(B) The resistance of a conductor depends on the material of the conductor.

(C) The resistance of a conductor depends inversely on its length.

(D) The resistance of a conductor depends inversely on its area of cross-section.

Choose the correct answer from the options given below:

(A), (B) and (C) only

(A), (B) and (D) only

(A), (C) and (D) only

(B), (C) and (D) only

✅ Correct Option: 2

Resistance opposes the flow of electrons, so (A) holds, and it varies with the material through its resistivity, so (B) holds. Since $R = \rho L/A$ , resistance is directly proportional to length, making (C) false, and inversely proportional to cross-sectional area, making (D) true.
