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!
