Q 2166880775.     Let `PM` be the perpendicular from the point `(1, 2, 3)` to

`x - y` plane. If `OP` makes an angle e with the positive

direction of the `z`-axis and `OM` makes an angle `phi` with the

positive direction of `x`-axis, where `O` is the origin then

`( theta` and `phi` are acute angles)
A

`tan theta = sqrt(5)/3`

B

`sin theta sin phi = 2/sqrt(14)`

C

`tan phi =2`

D

`cos theta cos phi = 1/sqrt(14)`
