What does UX design stand for?

User Experience design, often abbreviated as UX design, focuses on creating products and services that provide meaningful and relevant experiences to users. This involves a deep understanding of users' needs and behaviors to design interfaces that enhance usability and satisfaction.

In the context of UX design, practitioners conduct research to understand the user's journey, create personas, and develop prototypes that are tested and iterated upon to ensure the final product is intuitive and engaging. UX design is a crucial aspect of web and application development because it directly impacts user satisfaction and interaction with a product, aiming to improve the overall experience by making usability a priority.

The other options represent terms that are not recognized within the standard definitions related to design in the technology or software development fields, which further solidifies the understanding that User Experience design is the correct and relevant term in this context.
