Let the set $A=\{1,2,3,4,5,6\}.$ Below you have been provided with a list of binary relations from $A$ to A described extensionally. Choose all those that are reflexive.

$\{(1,5),(2,2),(2,6),(3,3),(3,5),(5,6),(6,2),(6,3),(6,6)\}$

$\{(1,1),(2,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,4),(5,2),(5,5),(5,6),(6,4),(6,6)\}$

$\{(1,1),(2,1),(2,4),(2,5),(3,2),(3,3),(3,6),(4,1),(4,4),(5,3),(6,6)\}$

$\{(1,1),(2,2),(2,3),(2,5),(3,3),(3,4),(4,4),(5,4),(5,5),(6,6)\}$
