The fuselage of a conventional aeroplane contributes
Answer: A
Correct answer: A destabilising yawing moment in sideslip
A conventional fuselage is a slender body with most of its side area ahead of the centre of gravity. In sideslip the resulting side force therefore acts forward of the centre of gravity and yaws the nose further from the relative wind - a divergent, destabilising moment.
The effect is present at every speed, since it depends on geometry and on sideslip rather than on dynamic pressure ratios. This is exactly why a fin is needed: its job is to overcome the fuselage's negative contribution and leave the total yawing moment derivative positive.
