A) all real numbers are rational numbers
Step-by-step explanation:
A)<em>√7 is a real number but it is not a rational number it is irrational number.</em>
<em>Thus, Option A is false.</em>

<em>Thus the option B is correct.</em>
C) Yes, All natural numbers are integers. Thus the option C is correct.
D) Yes, Every whole number is a real number. Thus the option D is correct.
Further,
Natural Number is the whole number except zero. i.e. 1, 2, 3, 4,....
Integers can be defined as the whole numbers including zero and positive whole numbers. i.e. ......,-4,-3, -2, -1, 0, 1, 2, 3, 4.....
Example: -546, 87855889, 0, etc.
Rational Number is the number in the form , where q≠0.
Example:
Real Number is the all numbers including natural, whole, integers, rational, irrational number except the imaginary numbers.
Example: , 5, √28, etc.
