Water is filled to height `h` in a fixed vertical cylinder placed on horizontal surface. At time `t = 0` a small hole a drilled at a height `h//4` from bottom of cylinder as shown. The cross section area of hole is a and the cross-section area of cylinder is `A` such that `A gtgt a`. Let the value of horizontal distance of point where the4 water fall on horizontal surface from bottom of cylinder be `x` as shown. Then from time `t = 0` till water comes out of hole, pick the correct statement:A. increasesB. decreasesC. remains constantD. increases and then decreases
