The CORRECT statement in the light of Bernoulli's theorem is that the

Explanation

According to Bernoulli's theorem, in a steady, ideal flow of an incompressible fluid with no viscosity, the sum of the pressure energy, kinetic energy, and potential energy per unit volume remains constant. This means that an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. Therefore, the correct statement is that the speed of the fluid is high at low pressure. Option B correctly reflects this relationship.Option A is incorrect because it states the opposite of what Bernoulli's theorem describes. Option C is incorrect because it contradicts the relationship established by Bernoulli's theorem, which links fluid speed and pressure. Option D is incorrect because Bernoulli's theorem is not applicable to turbulent flow; it is valid for streamline or laminar flow.
