Which of the following statements about the testing quadrants is TRUE?

The correct statement is B. According to the ISTQB CTFL syllabus, the testing quadrants help to categorize tests based on their purpose and whether they are technology-facing or business-facing, and whether they support the team or critique the product. Quadrant Q2 includes tests that are business-facing and support the team, such as automated acceptance tests produced during Behavior-Driven Development (BDD) and Acceptance Test-Driven Development (ATDD)​​ .

Quadrant Q3 includes business-facing tests that critique the product, such as exploratory testing, usability testing, and user acceptance testing. These tests are typically manual and focus on evaluating the product from a user perspective, rather than being part of a continuous integration process​​.

Quadrant Q4 includes technology-facing tests that critique the product, such as performance tests, security tests, and other non-functional tests, which can be automated but are not related to unit tests produced during TDD .
