The total pressure for a fluid is a. the sum of the hydrostatic and static pressures. b. the sum of the hydrostatic and dynamic pressures. c. the sum of the static and dynamic pressures. d. the sum of the static, dynamic, and hydrostatic pressures.

The option a is most appropriate

Explanation:

The total pressure due to liquid column at any place is the sum of

(i) pressure due to liquid column called hydrostatic pressure

(ii) the pressure due to air column above the liquid column, which is called the static pressure

Thus total pressure is the sum of hydrostatic and static pressure.

Thus the option a is most appropriate
