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 .
