If w is total load per unit area on a panel, D is the diameter of the column head. L is the span in two directions, then the sum of the maximum positive bending moment and average of the negative bending moment for the design of the span of a square flat slab, should not be less than

A] $$\frac{WL}{12}\left(L - \frac{2D}{3}\right)^2$$

B] $$\frac{WL}{10}\left(L + \frac{2D}{3}\right)^2$$

C] $$\frac{WL}{10}\left(L - \frac{2D}{3}\right)^2$$

D] $$\frac{WL}{12}\left(L - \frac{D}{3}\right)^2$$

For a circular slab carrying a uniformly distributed load, the ratio of the maximum negative to maximum positive radial moment is

If permissible compressive stress in concrete is 50 kg/cm$$^2$$, tensile stress in steel is 1400 kg/cm$$^2$$ and modular ratio is 18, the depth of the beam is
