TDD involves writing automated tests before writing the code, and pair programming involves two programmers working together at one workstation. The other options are not XP core practices: Sprint review (A) is a Scrum ceremony, product backlog grooming (D) is a Scrum activity, and retrospectives (E) are also a Scrum event.
