Moment of inertia of a body about two perpendicular axes $X$ and $Y$ in the plane of the lamina are $20 \text{ kg m}^2$ and $25 \text{ kg m}^2$ respectively. Its moment of inertia about an axis perpendicular to the plane of the lamina and passing through the point of intersection of $X$ and $Y$ axes is:

• A
  $5 \text{ kg m}^2$
• B
  $45 \text{ kg m}^2$
• C
  $12.5 \text{ kg m}^2$
• D
  $500 \text{ kg m}^2$
