An object is executing simple harmonic motion. What is true about the acceleration of this object? (There may be more than one correct choice.)
 
  A) The acceleration is a maximum when the displacement of the object is a maximum.
  B) The acceleration is a maximum when the speed of the object is a maximum.
  C) The acceleration is a maximum when the displacement of the object is zero.
  D) The acceleration is zero when the speed of the object is a maximum.
  E) The acceleration is a maximum when the object is instantaneously at rest.
