As we learned

Coplanar vectors -

Any two vectors \vec{a} and \vec{b} and a zero vector are always coplanar

- wherein

\vec{a} and \vec{b} are two vectors.

 

  Two vectors are always coplanar and null vector can be considered in every plane, so all three are coplanar.

\vec{a}\, \, and\, \, \vec{b} are not necessary to be collinear always

So, option (A)
