Identify the correct statements.

(A) Electric charge is quantized.
(B) Electric charge on any object is always an integral multiple of e.
(C) The coulomb force is weaker than the gravitational force.
(D) The coulomb force is a conservative force.

Choose the correct answer from the options given below:

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

The correct answer is Option (4) → (A), (B) and (D) only

(A) ✔ Electric charge is quantized: $q = n e$, $n$ integer.

(B) ✔ Electric charge on any object is always an integral multiple of $e$.

(C) ✘ Coulomb force is much stronger than gravitational force between elementary charges.

(D) ✔ Coulomb force is conservative: work done depends only on initial and final positions.

Correct statements: (A), (B), (D)
