To deliver quality service effectively, a service provider must deal with the needs of the business first rush in to solve the problem quickly deal with the human being first deal with the customer's business concerns first

 Deal with the human being first

Explanation:

Quality service is the part of the customer service that is provided to the customers for solving their queries , acknowledging advice, complaint handling etc.

Quality service requires the first step of handling the customer by patiently listening to their request or query and comfort them that their issue can be easily solved so that further steps can be taken.

Other options are incorrect because handling business requirements and customer's business is not part of quality service.Jumping directly to solve the issue of customer is not the correct step to start with.
