integers include both positive and negative numbers excluding fraction and decimal

Answer 2

C. integers

Explanation:

integers are similar to whole numbers : all numbers without any fractional part, but including negative numbers.

whole numbers only include positive numbers (incl. 0) without any fractional part.

natural numbers (I guess, that is the meaning of "counting numbers") are all positive numbers (but without 0) without any fractional part.

so, C is correct, because A contains also -1.
