○ convenience
○ systematic
○ simple random
○ cluster
○ stratified

Explanation:

In stratified sampling, the population is divided into subgroups (strata) based on some characteristic (here, car - size), and then samples are randomly selected from each stratum. In this case, cars are separated by size (strata) and 10 are selected from each size - group.

Stratified
