(B) We know that the magnitude of the resultant $R$ of two vectors $A$ and $B$ is given by the formula:$R = \sqrt{A^2 + B^2 + 2AB \cos 	heta}$Here,$R$ is maximum when $\cos 	heta$ is maximum.The maximum value of $\cos 	heta$ is $1$,which occurs when $	heta = 0^{\circ}$.Substituting $	heta = 0^{\circ}$ into the formula:$R_{\max} = \sqrt{A^2 + B^2 + 2AB(1)} = \sqrt{(A+B)^2} = A + B$.Therefore,the resultant is maximum when the angle between the two vectors is $0^{\circ}$.

For the resultant of two vectors $A$ and $B$ to be maximum,the angle between them should be (in $^{\circ}$)
