Answer:
C
Step-by-step explanation:
A number is rational if it can be expressed in the form
[tex]\frac{a}{b}[/tex] where a and b are integers
[tex]\sqrt{16}[/tex] = 4 = [tex]\frac{4}{1}[/tex] ← rational
[tex]\sqrt{25}[/tex] = 5 = [tex]\frac{5}{1}[/tex] ← rational
[tex]\sqrt{48}[/tex] = 4[tex]\sqrt{3}[/tex] ← irrational
[tex]\sqrt{100}[/tex] = 10 = [tex]\frac{10}{1}[/tex] ← rational
