Answer:

A. Surveying every 25,000th number

Step-by-step explanation:

If the numbers of people are assigned in order of 1 to 1 000 000 then the smallest sample would be obtained by conducting surveys every 25 000th numbers.

The calculation of the sample size would be made by dividing 1 000 000 by 25 000.

$\frac{1000000}{25000}= 40$

Therefore, the smallest sample selected would be 40 people.

If the surveys were made every 25th numbers, then the sample size would be:

$\frac{1000000}{25}= 40000$ people
