Is high adverse pressure gradient that occurs at a sharp leading edge?

(a) True

(b) False

I got this question during an online exam.

My question is from Viscous Flow topic in chapter Incompressible Flow over Airfoils of Aerodynamics

The correct answer is (a) True

Easy explanation: In some airfoils with small leading edge radius the stall is rather abrupt. The flow is well behaved at an angle of attack, say 5.5 degrees, but stalls with flow separation at the leading edge at 5.6 degrees because of the high adverse pressure gradient that occurs at such sharp leading edge.
