A thin rod of length Land mass M is bent at its midpoint into two halves so that the angle between them is 90°. The moment of inertia of the bent rod about an axis passing through the bending point and perpendicular to the plane defined by the two halves of the rod is

• A

  $\frac{{\mathrm{ML}}^2}{6}$

• B

  $\frac{\sqrt{2}{\mathrm{ML}}^2}{24}$

• C

  $\frac{{\mathrm{ML}}^2}{24}$

• D

  $\frac{{\mathrm{ML}}^2}{12}$
