Jim, an Inexperienced Salesperson, Informs One of His Potential Customers

Jim, an inexperienced salesperson, informs one of his potential customers that the laptop he is selling has a much faster processing speed than the competitor's laptop despite being aware that this is not true. The customer, however, remains unconvinced and does not make the purchase. Jim's behavior is considered unethical because he:

A) fails to be perceived as an expert by the customer.
B) fails to practice the hard-sell approach.
C) is unable to convince the customer to make a purchase.
D) exaggerates the benefits of his product.
E) is unable to meet his sales quota.
