The set of integers includes whole numbers like -2, -1, 0, 1, 2, etc., while irrational numbers are numbers that cannot be expressed as a simple fraction and have non-repeating, non-terminating decimal expansions.

1. **Square roots of integers**: Most square roots of integers are not integers. For example, √2, √3, etc., are irrational and not integers. Only perfect squares like √0 (which is 0) and √1 (which is 1) result in integers.

2. **Zero**: Zero is an integer, and it is neither rational nor irrational (it is a rational number because it can be expressed as 0/1).

3. **Negative integers**: Negative integers, like -1, -2, etc., are integers and are rational since they can be expressed as a fraction (e.g., -1 = -1/1).

4. **None**: This option suggests that no numbers meet the criteria stated in the question.

Based on this analysis, the correct answer is **none**. No numbers can be both integers and irrational numbers.
