What is the coefficient of pressure over the surface which is in shadow (no impact from the flow present)?

(a) Zero

(b) 1

(c) 2

(d) Infinite

I got this question during an online exam.

My query is from Newtonian Theory topic in portion Numerical Techniques for Nonlinear Supersonic Flow, Elements of Hypersonic Flow, Couette and Poiseuille Flow of Aerodynamics

Correct option is (a) Zero

For explanation I would say: For each body, the freestream particle impacts the surface in the frontal region. The rear side remains un – impacted by this flow. This portion is known as the ‘shadow’ where no impact pressure is felt. The coefficient of pressure in this region is zero.

For example for a flat plate that is kept at 90 degrees to the incoming freestream flow, the frontal region feels the impact, whereas the back surface is in shadow and the coefficient of pressure in this region is thus zero.
