Final answer:
A closed question during a sales call is one that invites a concise, direct response, such as a 'yes' or 'no' answer. The correct example of a closed question asked by salespeople in the given scenario is 'Do you have a commercial driver's license?'.
Step-by-step explanation:
A closed question typically requires a short, definitive answer, often a 'yes' or 'no', and does not provide an opportunity for extended discussion or elaboration. In the context of a sales call, a closed question used by salespeople might be aimed at confirming specific information about a customer's needs or situation. The question 'Which of the following is an example of a closed question asked by salespeople to customer during a sales call?' refers to the option that limits the customer's response to a simple, direct answer.
After reviewing the options provided, the correct answer is:
'Do you have a commercial driver's license?'
This question seeks a specific 'yes' or 'no' answer and does not invite further discussion, making it a clear example of a closed question.
