Correct option is (a) A region of high-speed flow is surrounded by a stationary fluid

To explain I would say: In mixing layers, the interaction of fast and slow moving fluids create turbulence. A turbulent wake is created by an object which disturbs the flow. When a high-speed flow is surrounded by a stationary fluid, the turbulent jet is formed.
