Step1: Understand sample size principle

Larger sample sizes (relative to the population) generally lead to more reliable results.

Step2: Compare the options

We have a population of 80,000. Option A is 800 ($\frac{800}{80000}=0.01$), Option B is 8000 ($\frac{8000}{80000}=0.1$), Option C is 80 ($\frac{80}{80000}=0.001$), Option D is 8 ($\frac{8}{80000}=0.0001$).
