Answer:
d. A 24/7 technical support hotline with a team that is knowledgeable about the product and business goals of the company's customers.
Step-by-step explanation:
The other software companies are already selling their product as a one off sale at retail stores. The president of the software company wants to sell his product as SaaS (software as a service) where customers will pay monthly subscription.
Customers are going to be paying more to use his product so he needs to get a competitive edge and give value that his competitors are not delivering to the customer.
Setting up a 24/7 customer support line with a team that can help the customer meet their business goals will give his product an edge.
