Matrix matching

	Column - I		Column - II
1)	If $A=\{a,b,c,d\}$ , then a relation  $R=\{(a,b),(b,a),(a,a)\}$ is	p)	Not symmetric
2)	Let $R=\{(1,3),(4,2),(2,4),(2,3),(3,1)\}$ be a relation on the set $A=\{1,2,3,4\}$  then the relation  $R$ is	q)	An equivalence relation
3)	The relation  $R=\{(1,1),(2,2),(3,3)\}$ on the set  $\{1,2,3\}$ is	r)	Reflexive and transitive
4)	If  R is a relation on set  of natural numbers defined by  $xRy\iff x$ divides y  then $R$  is	s)	Symmetric only
