The Magnetic Force Exerted on a Current-Carrying Wire in a Magnetic

The magnetic force exerted on a current-carrying wire in a magnetic field is the strongest when

A) the current is in the direction of the $\vec { B }$ field lines.
B) the current is in the direction opposite to the $\vec { B }$ field lines.
C) the current is at a 180° angle with respect to the $\vec { B }$ field lines.
D) the current is perpendicular to the $\vec { B }$ field lines.
E) the current is at a 0° angle with respect to the $\vec { B }$ field lines.
