(D) The force on a moving charge in a magnetic field is given by the Lorentz force formula: $\vec{F} = q(\vec{v} 	imes \vec{B})$.Here,the velocity vector $\vec{v}$ is directed vertically upwards (let this be the $+z$-axis).The magnetic field $\vec{B}$ is directed towards the north (let this be the $+y$-axis).Using the right-hand rule for the cross product $\vec{v} 	imes \vec{B}$:Point your fingers in the direction of $\vec{v}$ (upwards) and curl them towards $\vec{B}$ (north).The thumb points towards the west.Therefore,the force on the charge $+Q$ will be towards the west.

$A$ charge $+Q$ is moving upwards vertically. It enters a magnetic field directed to the north. The force on the charge will be towards
