Final answer:
The correct statement is that -5 is a rational number, but not an integer.
Step-by-step explanation:
The correct answer is A) -5 is a rational number, but not an integer.
A rational number is a number that can be expressed as a fraction, where both the numerator and the denominator are integers. -5 can be written as -5/1, which is a fraction and therefore a rational number. However, -5 is not an integer because it is not a whole number, it is a negative number.
An integer is a whole number, both positive and negative, and does not include fractions or decimals. -5 is not a whole number because it is a negative number, therefore it is not an integer.
In contrast, option B and option C are incorrect statements. -11 is an integer because it is a whole number, and 3 is an integer because it is also a whole number. However, both -11 and 3 can be expressed as fractions, making them rational numbers as well. Therefore, options B and C are not true statements.
