The equation of continuity (Av = constant) states that the product of cross-sectional area and velocity remains constant for an incompressible fluid in steady flow. As the area decreases, velocity increases to conserve mass flow rate.
Ref: NCERT Class 11 Physics, Thermal Properties and Gravitation.
The equation of continuity (Av = constant) assumes the fluid is incompressible, meaning its density remains constant, ensuring mass conservation in steady flow through varying cross-sections. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Fluid is incompressible. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
