What does UML stand for in software development?

The correct answer is Unified Modeling Language, which is a standardized modeling language used in software development to specify, visualize, and document the artifacts of a software system. UML provides a set of graphical notation techniques to create abstract models of system components and behaviors, which can enhance communication among stakeholders and improve the understanding of system designs.

UML supports various types of diagrams, including class diagrams, sequence diagrams, and use case diagrams, allowing developers, architects, and stakeholders to represent system components effectively. This is crucial in software engineering, where visual representation of complex systems can lead to better design decisions and clearer project documentation.

Other options do not accurately reflect the terminology or functions associated with UML. For example, Uniform Methodology Language, Universal Management Logic, and Unified Method Life Cycle are not recognized terms in the context of software modeling and do not align with the established concepts within software development practices.
