Part $3$: Directional relationship between B$-$field $\backslash$& magnetic force

A current$-$carrying wire is in a $\backslash ($ B $\backslash )-$field and experiences a magnetic force $(\backslash ($ F$\_\{$B$\}>0\backslash )).$ The magnetic force vector is shown below. Choose all the vectors that could represent the $\backslash ($ B $\backslash )-$field.
