In Agile practices, "TDD" stands for Test-Driven Development. This is a software development approach that emphasizes writing tests before writing the corresponding code. TDD operates on the principle of creating a test for a specific feature or piece of functionality, implementing the code that will make the test pass, and then refactoring the code as needed to improve its structure or efficiency.

This process not only ensures that code meets the defined requirements but also encourages a more robust design, as developers must think critically about how the code will be tested. TDD can lead to higher code quality, reduced bugs, and more comprehensive unit tests, ultimately resulting in a more reliable and maintainable codebase. The focus on testing right from the start introduces a specific discipline that underpins Agile methodologies, aligning development with user needs and facilitating quick iterations and improvements.

The other options do not accurately describe what TDD is in the context of Agile practices and do not align with the foundational concepts of Agile software development.
