A sphere can roll on a surface inclined at an angle $\theta$  if the friction coefficient is more than  $\frac{g}{7}$ tan$\theta$ . If a sphere is released from rest on  the incline

• A

  it will stay at rest

• B

  it will make pure translational motion

• C

  it will translate and rotate about the centre

• D

  the angular momentum of the sphere about  its centre will remain constant
