Which scenario increases the nose-up tendency from thrust?

Explanation:
The key idea is how the thrust line interacts with where the airplane’s weight is concentrated. Thrust creates a pitching moment about the center of gravity depending on how far the thrust line is from that center of gravity and on how effectively the tail can counteract that moment. When the center of gravity is toward the tail (aft), the aircraft is less stable in pitch and the tail’s counteracting moment is reduced in its effectiveness. That makes the same thrust-induced rotation more likely to raise the nose. So an aft center of gravity increases the nose-up tendency from thrust. Forward or neutral CGs keep the aircraft more stable, so they resist that nose-up effect more effectively.
