(C) Given,velocity of river $(v) = 2 ~m/s$.Density of water $(ho) = 1.2 ~g/cc = 1.2 	imes 10^3 ~kg/m^3$.Mass $(m)$ of each cubic metre of water is equal to its density multiplied by volume $(V = 1 ~m^3)$.$m = ho 	imes V = 1.2 	imes 10^3 ~kg/m^3 	imes 1 ~m^3 = 1.2 	imes 10^3 ~kg$.Kinetic energy $(K.E.)$ is given by the formula $K.E. = \frac{1}{2}mv^2$.Substituting the values:$K.E. = \frac{1}{2} 	imes (1.2 	imes 10^3) 	imes (2)^2$.$K.E. = \frac{1}{2} 	imes 1.2 	imes 10^3 	imes 4$.$K.E. = 2.4 	imes 10^3 ~J = 2.4 ~kJ$.

$A$ river of salty water is flowing with a velocity $2 ~m/s$. If the density of the water is $1.2 ~g/cc$,then the kinetic energy of each cubic metre of water is
