I believe C. Because it provides a more meaningful explanation
Here is the answer to you question
To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.

Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
