B. Is the "Loading Time" of any online application a functional or a non-functional requirement? Can the requirement engineers specify this property before the system is actually implemented, how?

Non functional

Explanation:

Loading time is a requirement that does not work in applications. There are many non-functional requirements, such as the usability, performance, and reliability of the application. The loading time falls into the display category. Generally, the loading time limit is specified in the application, and the application is exempt from the application for exit if the application loading time is too long
