Final answer:
Businesses typically have greater control over service quality with direct marketing channels because they can tailor services and manage experiences more effectively due to immediate customer feedback. The correct option is A.
Step-by-step explanation:
The statement that businesses exercise greater control over service quality when they use direct marketing channels to market their goods is generally considered true.
Direct marketing channels allow businesses to interact directly with consumers which enables them to receive immediate feedback, tailor their services more precisely to customer needs, and manage the customer experience more effectively.
By having fewer intermediaries or none at all, companies can maintain closer oversight of the entire process, from production to sale, thus ensuring that service quality remains high.
