The center of gravity can be defined as

1. The point to which the applied forces are supporting and gravity - acting on the aircraft
2. Point to which they are applied all the forces acting on the aircraft
3. Point to which they are applied drag force acting on the aircraft
4. ✓The point where the concentrated mass of the aircraft isCorrect answer

Explanation

In physics and mass and balance, the Center of Gravity (CG) is the theoretical point at which the entire mass of the aircraft is assumed to be concentrated.
