You are meeting with a user at a financial institution to gather app requirements. The app must meet the following requirements: - Be enabled for mobile use. - Respond in less than five seconds…

Non-functional requirements describe how a system performs or its quality attributes, such as performance (e.g., 'respond in less than five seconds') and security (e.g., 'all data transmitted over the network must be encrypted').

Feasibility requirements assess whether a project is technically, economically, or operationally viable, not a characteristic of the application itself.

Functional requirements describe specific behaviors or functions of a system, specifying what the system should do, such as being 'enabled for mobile use' as a core capability.

Exception requirements define how the system should behave under abnormal conditions or errors, which is not directly captured by the given statements.

Compliance requirements specify adherence to laws, regulations, or standards, which while related to encryption, is a broader category and not the primary classification for 'encrypted data transmission' when 'non-functional' is a more direct fit.
