Best answer
Answer: D. Energy
Answer: (d) Energy
Bernoulli’s theorem is the law of conservation of energy applied to an ideal fluid in streamline flow: \(P + \frac{1}{2}\rho v^2 + \rho g h = \text{constant}\), i.e. pressure energy + kinetic energy + potential energy per unit volume remains constant along a streamline.
