Answer:
D. All of these
Step-by-step explanation:
Customers are always interested in putting/matching a face to an online business. In other words, it will be difficult to transact business with an ebusiness if the business owner is unknown, unavailable and not accessible. Also, customers tend to doubt ebusinesses with no track record easily determined by the verifiable testimonials of the previous customers.
A business owner who does not respond to customer enquiry online can be said to be available but inaccessible. Both availability and accessibility, as well as customer testimonials, are key to building trust in an ebusiness.
