A centre of gravity position close to its aft limit will cause the aircraft to
- pitch nose down and increase its longitudinal stability.
- pitch nose up and decrease its longitudinal stability.
- pitch nose up and increase its longitudinal stability.
Explanation from PART66Online
Moving the centre of gravity aft shortens the arm between the CG and the tailplane, reducing the restoring pitching moment and therefore decreasing longitudinal stability. The reduced tail download also lets the nose ride higher, giving a nose-up tendency. A forward CG would do the opposite, increasing stability and stick forces.

because you have to imagine a force pushing down the airplane's aft, while the force is pushing what happen to the nose? pitch nose up and decrease its longitudinal stability
hope it is helpful
