Explanation / Answer

Here R={(1,1),(2,1),(2,2),(2,3),(3,1),(3,3)}

is a relation on {1,2,3}

so Here domain ={1,2,3} and range ={1,2,3}

R xR =r^2 is the cartisian product where each element of each order pair   is associated with each element of second element of each order pair of second relation.

So here

R X R = {(1,1),(2,1),(2,2),(2,3),(3,1),(3,3)} x {(1,1),(2,1),(2,2),(2,3),(3,1),(3,3)}

={(1,1),(2,1),(2,2),(2,3),(3,1),(3,3)}

or first option is correct answer.

This is the very first question number 7).
