[B]. the flow around any path in the fluid is zero for continuous flow
[C]. the rate of change of ψ with distance in an arbitrary direction, is proportional to the component of velocity normal to that direction
[D]. the velocity vector may be found by differentiating the stream function
[E]. all the above.

It is a scalar function of space and time such that its partial derivative with respect to any direction gives the velocity component at right angles to this direction.

The flow velocity components can be expressed as the derivatives of the scalar stream function. The stream function can be used to plot streamlines, which represent the trajectories of particles in a steady flow. The two-dimensional Lagrange stream function was introduced by Joseph Louis Lagrange in 1781.
