The correct answer is:
Both I and II
A simple pendulum in practice, consists of a heavy but small sized metallic bob suspended by a light, inextensible and flexible string.
It will oscillates simple harmonically, only if
(I) the size of the bob is negligible as compare to the length of the string of pendulum.
(II) the angle between the normal drawn at the mean position and string at extreme point or angular amplitude is less than $10^{\circ}$.
Thus, both the statements are correct.
