As we learned

Negative of a vector -

The negative of a vector is collinear with vector itself.

- wherein

-\vec{a} is collinear with \vec{a}

 

  \because \vec{a}\, and\, \vec{b} are are negative vector of each other, so they will be collinear.

And we know vectors are always coplanar, so

Option (A)
