Center of Pressure(CP) The center of pressure is:

A)The point at which the Total Aerodynamic Force acts
B)The point where the lift force acts
C)The point where the resistance force acts

Only one answer is correct,i think is B or A but the question is really strange.
The fact that Total Aerodynamic Force is capitalized indicates it is a term that can be researched:

Total Aerodynamic Force includes drag, therefor the answer is B)
the point where the lift force acts.
