Which of the following best describes an Increment of working software?

TheScrum Guidedefines an Increment as "a concrete stepping stone toward the Product Goal" that is usable and meets the Definition of "Done": "Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together." Option E captures this—new, usable features that build on previous work. Option A (test suite) is a tool, not an Increment. Option B (UML diagrams) is documentation, not working software. Option C (task decomposition) is planning, not a product. Option D (UI design) isn’t necessarily usable software. Thus, E best describes an Increment.
