Given below are two statements: 
Statement I: If the acceleration of a particle is directed towards a fixed point, and proportional to the distance from that point – the motion is SHM.
Statement II: During SHM, the kinetic energy of the particle oscillates at twice the frequency of the SHM.
1. Statement I is incorrect and Statement II is correct.
2. Both Statement I and Statement II are correct.
3. Both Statement I and Statement II are incorrect.
4. Statement I is correct and Statement II is incorrect.
