An object swinging on the end of a string forms a simple pendulum. Some students (and some texts) often cite the simple pendulum's motion as an example of SHM. That is not quite accurate because the motion is really
approximately SHM only for small amplitudes
exactly SHM only for amplitudes that are smaller than a certain value
approximately SHM for all amplitudes.
None of the above

Correct option is A)
An object performing SHM moves along a straight path.
For large amplitudes, a pendulum moves in a curved path.
