d. $\frac{1}{5}$

Step-by-step explanation:

The square number between 1 and 20 = 1,4,9,16

The number of squares between 1 and 20 = 4

The total numbers between 1 and 20= 20

The probability that the number selected is the square of a natural number is given by :-

$P=\frac{\text{square numbers}}{\text{total numbers}}\\\\\Rightarrow\ P=\frac{4}{20}=\frac{1}{5}$

Hence, The probability that the number selected is the square of a natural number is $\frac{1}{5}$
