Answer:

Option B.

Explanation:

Given:

r=(√(3),√(5),√(7),√(13))

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

$R=\{(a,b):a\in R,b\in R\}$

Since r is not a set of ordered pairs, therefore r is not a relation.

Thus, the correct option is B.
