Answer:
Option B.
Step-by-step explanation:
Given:
[tex]r=(\sqrt{3},\sqrt{5},\sqrt{7},\sqrt{13})[/tex]
r is a set of rational numbers.
We need to find the reason why r is not a relation.
A relation is a set of ordered pairs, where x-coordinate is domain and y-coordinate is range. It is defined as
[tex]R=\{(a,b):a\in R,b\in R\}[/tex]
Since r is not a set of ordered pairs, therefore r is not a relation.
Thus, the correct option is B.
