Vector Algebra

Vectors $a=i^+2j^ +3k^,b=2i^−j^ +k^$ and $c=3i^+j^ +4k^,$ are so placed that the end point of one vector is the starting point of the next vector. Then the vector are (A) not coplanar (B) coplanar but cannot form a triangle (C) coplanar and form a triangle (D) coplanar and can form a right angled triangle
