A)The x component of vector $\vec { A }$ is equal to the x component of vector $\vec { B }$
B)The y component of vector $\vec { A }$ is equal to the y component of vector $\vec { B }$
C)The x component of vector $\vec { A }$ is equal to the y component of vector $\vec { B }$
D)The y component of vector $\vec { A }$ is equal to the x component of vector $\vec { B }$

Since vector $\vec { A }$ is along the +x-axis, its y component is 0. Similarly, vector $\vec { B }$ is along the +y-axis, so its x component is 0. Therefore, the y component of $\vec { A }$ (which is 0) is equal to the x component of $\vec { B }$ (which is also 0).

Vector A⃗\vec { A }A Is Along the +X-Axis and Vector B⃗\vec { B }B

Vector $\vec { A }$ Is Along the +X-Axis and Vector $\vec { B }$
