Step-by-step explanation:
The time that elapses between asking a question and receiving the answer is called response latency. It refers to the delay or lag time between the question being posed and the response being delivered. This term is often used in the context of computer systems or customer support, where the speed of response is important for user satisfaction.
For example, if you send an email to customer support and it takes 24 hours for them to respond, the response latency is 24 hours.
Therefore, the correct answer is option a. response latency.
