Explanation:

Step1: Identify valid numbers

We consider two - digit numbers from the random - digit table. Numbers should be between 01 and 70. Ignore numbers greater than 70 and repeated numbers.

Step2: Analyze the given random - digit table

Starting from the left of the random - digit table 81232 43939 84583 23840 05995. The first two - digit number 81 is greater than 70, so we ignore it. The next number 23 is between 01 and 70, so it is part of the sample. The next two - digit number 24 is also between 01 and 70, so it is part of the sample. The number 39 is between 01 and 70 and is part of the sample. The second 39 is a repeat of the previous 39, so we ignore it. The number 58 is between 01 and 70, so it is part of the sample. The number 32 is between 01 and 70, so it is part of the sample.

Answer:

D. 23, 24, 39, 58, 32
