According to Bernoulli's equation \[\frac{P}{\rho g}+h+\frac{1}{2}\,\frac{{{v}^{2}}}{g}=\text{constant}\] The terms A, B and C are generally called respectively:

• A.             Gravitational head, pressure head and velocity head
• B.             Gravity, gravitational head and velocity head
• C.             Pressure head, gravitational head and velocity head
• D.             Gravity, pressure and velocity head
