Given below in Column I are the relations between vectors a,b and c and in Column II are the orientations of a, b and c in the XY - plane . Match the relation in Column I to correct orientations in Column II.

Explanation

Consider the adjacent diagram in which vectors A and B are corrected by head and tail .
Resultant vector C= A+B
(a) from (iv) it is clear that c=a+b
(b) from (iii) `c+b=arArra-c=b`
(c) from (i) `b=a+crArrb-a=c`
(d) from (ii) `-c=a+brArra+b+c=0`
