Answer 1

When a kink occurs in a pipe during bending, it creates an obstruction in the flow path. This obstruction can lead to increased resistance and turbulence in the fluid flow, resulting in a higher pressure drop.
Pressure drop is the loss of pressure as a fluid flows through a pipe or conduit, and it is influenced by factors such as the geometry of the pipe and the smoothness of its interior surfaces.
The kink disrupts the smooth flow of fluid, causing turbulence, increased friction, and restrictions. This, in turn, leads to a higher pressure drop as the fluid encounters resistance while passing through the kinked portion of the pipe.
Increased pressure drop can have several adverse effects, including reduced efficiency of the fluid system and the potential for damage to pumps and other components due to excessive resistance.

Here, option 3 is correct.
