Assertion: Three points with position vectors `vecas,vecb,vecc` are collinear if `vecaxxvecb

Assertion: Three points with position vectors `vecas,vecb,vecc` are collinear if `vecaxxvecb+vecbxxvecc+veccxxveca=0` Reason: Three points A,B,C are collinear Iff `vec(AB)xxvec(AC)=vec0` (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.
