Hint: In order to answer this question, we will first mention the correct options for the motion of the torsional pendulum as the multiple options is correct. And then we will explain the motion of the torsional pendulum by representing it numerically.
Complete answer:
The motion of a torsional pendulum is periodic, oscillatory and angular simple harmonic.
Torsional Pendulum motion is defined as the motion of a rigid body supported by a massless inextensible string.
Torsional Pendulum is the part of Physical Pendulum, which is having a Time Period of,
$ T = 2\pi \sqrt {\dfrac{I}{K}} $
where, $ I $ is the moment of inertia, and
$ K $ is the torsion constant.
Torsion causes a periodic reversal in the direction of the disc in the case of a torsion pendulum. The body's centre of gravity, on the other hand, remains constant. Torsion oscillation refers to the sort of oscillation caused by a torsion pendulum.
This Motion is angular Simple Harmonic Motion. Since it is Angular S.H.M, it must be Oscillatory. Also, it must be Periodic.
Simple Harmonic Motion does not involve Rotational Analogy, hence it cannot be simple Harmonic Motion.
Hence, the correct options are (a) periodic, (b) oscillatory and (d) angular simple harmonic.
Note:
The Pendulum rotates clockwise and then counter clockwise. Heat affects the period of oscillation, which is one of the challenges with traditional pendulums keeping track of time. Depending on the temperature, the pendulum is somewhat longer or shorter.
