Bernoulli’s principle assumes non-viscous flow, not high viscosity, as viscosity causes energy loss, violating the energy conservation assumption. The incorrect statement is that it applies to highly viscous fluids. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It applies to highly viscous fluids. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
