Pick up the correct statement from the following:

• If the bed level is above N.S.L. the canal is called fully in baking and the berms are designed as 3 d where d is full supply depth of water (F.S.D.)
• Area of canal in cutting = BD + Sd2 where B = bed width, d = depth of cutting and S is the side slope
• Area of the bank of canal = B1d1 + Sd2 where B1, d1 and S are the width of bank, height of the bank above N.S.L. and side slope respectively
• If F.S.L. is above N.S.L the canal is called partly in cutting and partly in filling and berms are designed as 2d where d is full supply depth
• All the above.
