A vector quantity $V$ is split into two perpendicular components $X$ and $Y$. The angle between $V$ and component $X$ is $\theta$. The angle between component $X$ and the vector $V$ is increased from $0^\circ$ to $90^\circ$. As $\theta$ is increased in this manner, what happens to the magnitudes of $X$ and $Y$?
- AX increase, Y increase
- BX increase, Y decrease
- CX decrease, Y increase
- DX decrease, Y decrease
