The correct option is (a) True

Explanation: The flow is assumed to be axisymmetric throughout this range. A timed pent stream function vorticity formulation is adopted. The solution is obtained by constructing a finite difference approximation to the vorticity transport equation on an expanding spherical polar grid system.
