Water is flowing through a pipe as shown in figure. If `P_(1), P_(2) and P_(3)` are pressures and `v_(1), v_(2) and v_(3)` are velocities of water at the different sections as shown in figure, then
A. `P_(1) gt P_(2) gt P_(3)`
B. `v_(1) gt v_(2) gt v_(3)`
C. `P_(2) gt P_(1)`
D. `v_(3) gt v_(2) gt v_(1)`
