Which of the following statements is TRUE regarding equivalence class testing?

Deriving test inputs from boundaries of functional specifications describes boundary value analysis (BVA), which is a related but distinct black-box testing technique that focuses on edge values rather than representative partitions.

Stateless behavior of a process implemented in a function describes a characteristic associated with functional or unit testing concepts, not equivalence class testing, which is concerned with grouping inputs into valid and invalid partitions.

The fundamental principle of equivalence class testing is that all values within a partition (equivalence class) are assumed to be processed identically by the system under test. Therefore, testing one representative value from each partition is sufficient to validate the behavior of the entire class, reducing the total number of test cases needed while maintaining coverage.

Testing communications protocols and graphical user interfaces is a characteristic associated with state transition testing (also called finite state machine testing), which models system behavior based on states and transitions, not equivalence partitioning.
