A rigid massless tetrahedron is placed such that vertex O is at the origin and the other three vertices A, B, and C lie on the coordinate axes as shown in the figure. The body is acted on by three point loads, of which one is acting at A along x-axis and another at point B along y-axis. For the body to be in equilibrium, the third point load acting at point O must be

A

along z-axis

B

in x - y plane but not along x or y axis

C

in y - z plane but not along y or z axis

D

in z - x plane but not along z or x axis
