Answer: Option A.

Explanation:

Rationals numbers are defined as all those numbers which can be written as fractions, which have the form:


(a)/(b)

Being the numerator a and the denominator b integer numbers.

The numbers in the option A are rational numbers, because:


-4=(-4)/(1)\\\\0=(0)/(1)\\\\(1)/(4)\\\\\sqrt{(9)/(4)}=(3)/(2)

All these number can be written as fractions, therefore all of them are rational numbers.
