Fish : Shoal :: Lion : ............ Select the correct option to complete the analogy.

Identify the grammatically correct sentence:

A Newtonian fluid is transported through a smooth horizontal pipe of diameter 1 m at a flow rate of 3.14 m³/s. The length of the pipe is 1 km. The viscosity of the oil is 0.02 Pa.s and its density is 800 kg/m³. Consider the Darcy friction factor (\( f \)) for turbulent flow in a smooth pipe is given as
\[ f = \frac{0.316}{{Re}^{0.25}} \] where \( {Re} \) is the Reynolds number.
Assuming fully-developed flow in the pipe, the pressure drop due to the frictional effect is .......... kPa (rounded off to two decimal places).
