As we learned,

Collinear Vectors -

Like and unlike vectors are collinear

-

 

 \vec{a} \, \, and\, \, \vec{b} are like or unlinke vectors when

\vec{a}=\lambda \vec{b}

where \lambda>0 for like vectors & \lambda<0 for unlike vectors.

And for collinear vectors, vectors should be any of like or unlike.

(A), (B), & (D) all satisfy \vec{a}=\lambda \vec{b}

But (C) does not satisfy

So, option (C)
