The moment of intertia of a solid cylinder of mass \(M\), length \(2 R\) and radius \(R\) about an axis passing through the centre of mass and perpendicular to the axis of the cylinder is \(I_1\) and about an axis passing through one end of the cylinder and perpendicular to the axis of the cylinder is \(I_2\), then

  1. A \(I_2 < I_1\)
  2. B \(I_2-I_1=M R^2\)
  3. C \(\frac{I_2}{I_1}=\frac{19}{12}\)
  4. D \(\frac{l_2}{l_1}=\frac{7}{6}\)
