Answer 1

I made a family tree according to the question.

And the answer is Z.
If any doubt then ask me in my following family table.

I used a box for male and circle for female, cross for married couples and single horizontal line for brother sister, vertical line for son or daughter.

So clearly we can see that z is the brother in law of R.

You can ask if any doubt.
