Which of the following statements are true for diamagnetic substances?

(A) They are feebly repelled by magnet
(B) They are feebly attracted by magnet
(C) Susceptibility is small and positive
(D) Susceptibility is small and negative

Choose the correct answer from the options given below:

(A) and (D) only

Diamagnetic substances are lightly repelled by magnets and tend to move from stronger to weaker parts of a magnetic field.

Magnetic susceptibility is small and negative i.e. -1 ≤ χ ≤ 0.
