Answer 2

• Option (d) is correct answer.

$\because \: \: \text{Integer can be expressed as \: \purple{a/b}.} \\ \text{</p><p> \underline{\underline{For example :}} \: (\orange{-8}) is an integer.} \\ \text{</p><p>And, \purple{-16/2} is rational number but is equal to \orange{-8}.}$

Thus,

♦ Every Integer is a Rational Number.

For reference, Study the following definitions :

• Integers - A collection of numbers in which all negative numbers, zero, and positive numbers are included, but not a fraction.
• Whole number - Those numbers except negative, but including 0 & fractions, are whole numbers.
• Natural numbers - All Integers greater than one, but not decimals, are natural numbers. It can be said as Counting Numbers.
• Rational Numbers - Those numbers in form of a/b such that (a,b) are Co-Prime, b ≠ 0.
