What is the position of stagnation point, when a cylinder is placed in the wind tunnel?

(a) Lower part

(b) Upper part

(c) Middle part

(d) No stagnation point

I got this question during a job interview.

My question comes from Lifting Flow over Cylinder topic in section Inviscid & Incompressible Flow of Aerodynamics

Best answer
The correct answer is (a) Lower part

The best I can explain: The stagnation point moves to the lower part of the cylinder, similar to the theoretical flow. If the spin is sufficiently increased the stagnation point lifts off the surface. Position of stagnation point is a strong function of circulation, with zero circulation stagnation point lies at zero.
