0Out of the following functions representing motion of a particle, which represents SHM ?
(1) \( y=\sin \omega t-\cos \omega t \quad \) (2) \( y=\sin ^{3} \omega t \)
(3) \( y=5 \cos \left(\frac{3 \pi}{4}-3 \omega t\right) \)
(4) \( y=1+\omega t+\omega^{2} t^{2} \)
(A) Only (1)
(B) Only (4) does not represent SHM
(C) Only (1) and (3)
(D) Only (1) and (2)
