Explanation:

Step1: Identify valid numbers

We ignore numbers greater than 90. For the given random - digit table values 92200 99401 54473 34336 82786, we consider two - digit groups.

Step2: Select first 5 valid numbers

Starting from the left, we get valid two - digit numbers within the range 01 - 90. The first valid number is 20, then 09, then 01, then 54, then 47.

Answer:

C. 20, 09, 01, 54, 47
