A body executes simple harmonic motion the potential energy (PE),  the kinetic energy (KE) and total energy (TE) are measured as a function of displacement x. Which of the following statement is true?

At x=0, KE is maximum and PE is minimumkinetic energy of simple harmonic oscillator is = K=12mω2(A2-x2) When x=0,  K=12mω2(A2)  this is maximum energy  potential energy of simple harmonic oscillator is = PE==12mω2(x2)  When x=0, PE=0 total energy of a simple harmonic oscillator =TE=12mω2(A2)=constant
