(D) rational number is a number that can be expressed in the form $\frac{p}{q}$,where $p$ and $q$ are integers and $q 
eq 0$.$1$. $\sqrt{7}$ is an irrational number because $7$ is not a perfect square.$2$. $3\pi$ is an irrational number because $\pi$ is irrational.$3$. $0.101000...$ is a non-terminating and non-repeating decimal,which makes it an irrational number.$4$. $0.25$ can be written as $\frac{25}{100} = \frac{1}{4}$,which is in the form $\frac{p}{q}$.Therefore,$0.25$ is a rational number.
