(C) The total number of possible outcomes when selecting a number from $1$ to $100$ is $100$.The prime numbers between $1$ and $100$ are: $2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97$.Counting these,we find there are $25$ prime numbers in total.The probability of an event is given by the formula: $P(E) = \frac{	ext{Number of favorable outcomes}}{	ext{Total number of possible outcomes}}$.Therefore,the required probability is $\frac{25}{100} = \frac{1}{4}$.
