The Center of Gravity (CG) of an aircraft is a crucial concept in mass and balance, representing a specific point where the total weight of the aircraft is considered to act. It is the balance point that affects the aircraft's stability and control during flight. The CG is unique to each aircraft and is determined based on its design, loading, and weight distribution.

The correct answer highlights that the CG acts through a specific point, known as the Center of Gravity. This point is calculated based on the distribution of weight throughout the aircraft and is essential for ensuring that the aircraft remains balanced and controllable. A properly calculated CG ensures that the aircraft can perform optimally, maintaining stability during flight.

In contrast, suggesting that the CG acts at the tail section, one point on the wing, or at the nose of the aircraft would not be accurate. These locations do not represent the balance point of the aircraft's weight. Each of these locations could have certain weight distributions, but none can define the CG, which is assessed analytically based on the entire aircraft's weight and balance configuration. The CG is fundamentally a singular point derived from the overall mass distribution within the aircraft, making it essential for flight operations and safety.
