Answer:

A. \(\sqrt{1}\)

Step-by-step explanation:

We have been given four numbers. We are asked to choose the rational number.

We know that a number is rational, if we can write it as a fraction.

A. \(\sqrt{1}\)

\(\sqrt{1^2}=1\)

Therefore, \(\sqrt{1}\) is a rational number.

B. \(\sqrt{2}\)

\(\sqrt{2}=1.414213562373095\)

Since \(\sqrt{2}\) has non terminating decimals, therefore, it is an irrational number.

C. \(\sqrt{3}\)

\(\sqrt{3}=1.7320508075688773\)

Since \(\sqrt{3}\) has non terminating decimals, therefore, it is an irrational number.

D. \(\sqrt{5}\)

\(\sqrt{5}=2.2360679774997897\)

Since \(\sqrt{5}\) has non terminating decimals, therefore, it is an irrational number.
