The condition that two non zero vectors are collinear is

Angle between them zero

$\overrightarrow{A}\times \overrightarrow{B}=0$

So A, B, D are not correct

If two vectors are collinear then the two vectors are parallel to each other then the angle between them is 0.

$\therefore \overline{A}\times \overline{B}=\left|A\right|\left|B\right|\sin \theta =\left|A\right|\left|B\right|0=0$
