A) $\mathbf { u } = \frac { 3 } { 5 } \mathrm { i } + \frac { 4 } { 5 } \mathrm { j }$
B) $\mathbf { u } = 15 \mathbf { i } + 20 \mathbf { j }$
C) $\mathbf { u } = - \frac { 4 } { 5 } \mathrm { i } - \frac { 3 } { 5 } \mathrm { j }$
D) $\mathbf { u } = \frac { 5 } { 3 } \mathbf { i } + \frac { 5 } { 4 } \mathbf { j }$
