If a line `(x-x_1)/a_1=(y-y_1)/b_1=(z-z_1)/c_1` intersect the plane `a_2x+b_2y+c_2z+d_2=0` at one point only, then:

A.

`a_1a_2+b_1b_2+c_1c_2=0`

B.

`a_1a_2+b_1b_2+c_1c_2!=0`

C.

`a_1/a_2=b_1/b_2=c_1/c_2`

D.

none of these

If line intersect a plane at one-point means plane does not contain line and also line is not parallel to plane so `a_1a_2+b_1b_2+c_1c_2!=0`
