Center of gravity is defined as the theoretical point
1, From which all horizontal measurements are made.
2, Where all of the aircraft lift is considered to be concentrated.
3, Where all of the aircraft weight is considered to be concentrated

The center of gravity is the theoretical point where the entire weight of the aircraft is considered to be concentrated.
Take a look at chapter 8 of the Handbook of Aeronautical knowledge

CG is the point in an object at which all of the weight is considered to be concentrated. The CG may be expressed in inches from the datum.
I can see how students might choose 1 since they'd be thinking of the arm. Answer #2 is also wrong -- it's the center of lift and is located along the chord line of an airfoil.
Hope that helps.
