In psychology the population is who the sample can be generalized to and the sample is the people in the study I haven't done this in maths, but I figure they probably are the same thing so here is how I would answer in psychology
1. A Because you can't generalize the results to people who don't buy cars because you only asked people who did
2. B Because the sample is the people you actually ask
3.B Because they want to know about everyone that visited, but didn't ask a single person who didn't buy
4.A Because they didn't try to represent the subsets of the population in their correct proportions to the entire population so it's not stratified, it's not systematic because the population was not arranged in any way, before starting the survey it is random because they only surveyed the population, but still not stratified for the reason I mentioned before.I was thinking it could be convenience sampling instead of random, but than I realized how small the population is so it's not convenience
