Concept:Integers are whole numbers that have no fractional part. They include positive numbers, negative numbers, and zero.Explanation:The given set is $\{-10, -4, 0, \frac{1}{4}, 2\frac{1}{4}, 45, 100\}$.We need to pick out only the integers from this set.$-10$ is an integer.$-4$ is an integer.$0$ is an integer.$\frac{1}{4}$ is a fraction, so it is not an integer.$2\frac{1}{4}$ is a mixed number with a fractional part, so it is not an integer.$45$ is an integer.$100$ is an integer.Therefore, the integers in the set are $\{-10, -4, 0, 45, 100\}$.Answer:Option A: $\{-10, -4, 0, 45, 100\}$
