Detailed Solution

An integer is a number that can be positive, negative, or zero, but it cannot be a fraction. Whole numbers are the numbers starting from zero and include all positive numbers. Unlike whole numbers, integers do not include decimal numbers.

A rational number is a number that can be expressed as a fraction, or as the ratio of two integers. Essentially, a rational number is the quotient of two integers.

An irrational number, on the other hand, cannot be written as a fraction. It is a number that cannot be expressed as the ratio of two integers.

Real numbers are a set of numbers that include both rational numbers and irrational numbers.

A natural number refers to numbers starting from one and includes all positive whole numbers.

Every integer is a real number and a rational number, but it is not an irrational number or a natural number.

Therefore, the correct answers are Option (A) and Option (B).
