An isosceles triangular piece is cut from a square plate of side \( l \). The piece is one-fourth of the square and mass of the remaining plate is \( M \). The moment of inertia of the plate about an axis passing through \( O \) and perpendicular to its plane is
(1) \( \frac{M l^{2}}{6} \)
(2) \( \frac{M l^{2}}{12} \)
(3) \( \frac{M l^{2}}{24} \)
(4) \( \frac{M l^{2}}{3} \)
