A portion of a tube is shown in the figure. Fluid is flowing from cross-section area `A_(1)` to `A_(2)`. The two cross-sections are at distance `'l'` from each other. The velocity of the fluid at section `A_(2)` is `sqrt((gl)/(2))`. If the pressures at `A_(1)` & `A_(2)` are same, then the angle made by the tube with the horizontal will be:

A

`37^(@)`

B

`sin^(-1)'(3)/(4)`

C

`53^(@)`

D

`cos^(-1)'(3)/(4)`
