The rotor of a ship rotates in clockwise direction when viewed from stern and the ship takes a right turn. The effect of gyroscopic couple acting on it will be to raise the stern and lower the bow.

Rotor rotation is + X (or +i) because when we fold our four fingers in rotor direction from stern side Thumb shows +x. For a right turn, it is -Y (or -j) direction. Direction of gyro = (+i. -j) = -k (clockwise direction) which gives bow down and raise (by folding fingers in clockwise direction).

No, option stern is lower and bow is rise.

When we see from the back direction then the direction of the velocity is away from you then the effect of right turn is observe in top view this effect on the gyroscopic couple which is acting opposite to the change in motion so the effect of gyroscopic is the ship is move in anticlockwise direction effect is seen in front view so the in front figure is move in anticlockwise direction so the raise the stern and lower the bow.
