Step-by-step explanation:
The other two requirements, regulatory and business, can be classified as both functional and non-functional requirements depending on their nature.
Regulatory requirements, such as licensing requirements and safety and environmental standards, can be considered as non-functional requirements, as they focus on the overall behavior and characteristics of the system rather than specific functionalities. These requirements are usually imposed by external entities, such as government regulations or industry standards, to ensure compliance and meet certain criteria.
On the other hand, business requirements can be classified as functional requirements as they directly relate to the functionalities and processes of a system. They define what the system should do and how it should function to meet the needs and goals of the business. For example, business requirements may include features, workflows, or specific functionalities that are necessary for the system to effectively support the business operations.
