Question

Which of the following options represents the above figure?

• A. Prime numbers
• B. Odd numbers
• C. Even numbers
• D. Square numbers

Answer 1

The correct option is D Square numbers

Consider figures (i), (ii), (iii) and (iv).
Count the number of small squares in each of these figures.
We get the numbers 1, 4, 9 and 16.
But,
$1=1^2$
$4=2^2$
$9=3^2$
$16=4^2.$
Thus, the number sequence 1, 4, 9, 16 represents square numbers or perfect squares.
