Choose the correct answer:Which behavioral process can be modeled by a FunctionBehavior?

A FunctionBehavior in UML is a specialized form of behavior that specifies a function that, when executed, yields results influenced only by its input arguments and its internal attributes, without any side effects (e.g., altering global variables or I/O operations). This makes it stateless. Among the options provided:

Ainvolves I/O operations which are not covered under FunctionBehavior as it implies side effects.

Bdeals with environmental inputs and actuator control, not just function computation.

Ccould be considered but implies a state change which again might involve side effects, depending on the implementation.

Dpurely involves calculation based on input parameters, which fits the definition of FunctionBehavior perfectly, as it is a stateless computation.

Eis incorrect because UML indeed includes the concept of FunctionBehavior.
