Answer:
D. 
Step-by-step explanation:
Consider the set

This set consists of four ordered pairs.
The first numbers in these pairs are
These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are
These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and
