Not attempting could lead to not getting it at all. attempting to can potentially get you the money which is an advantage
if its to refuse the product, the best option would be c. give an excuse. however, that method may not always work so i believe b. accept the product but do not smoke it would be the best way out of it. the question is asking for a way to refuse the product so it is more likely to be c because a,b, and d all end up with said person obtaining the product. i hope this helped!
