Answer:
B)Missionary salesperson
Step-by-step explanation:
A missionary salesperson usually contacts individuals that will influence the purchase decision of other individuals but not themselves.
It's easier to explain using an example; a salesperson contacts your high school teacher about a new textbook and then that teacher tells his students to buy the new textbooks. The missionary salesperson never contacted the actual customers of his textbooks, he contacted the individual that can influence their purchase decision. The same applies to pharmaceutical representatives that contact doctors so that they prescribe the drugs their company produces. The doctor is not the customer, but he will influence the purchase decision made by others.
