B) Safelight evaluation
C) Patient compliance determination
D) Test for darkroom light leaks

C
Explanation: A) Quality assurance is defined as the planning, implementation, and evaluation of procedures used to produce high-quality radiographs with maximum diagnostic information (yield) while minimizing radiation exposure. Establishing a quality control program for radiographic procedures helps to increase the quality of radiographs produced and decrease the incidence of retake radiographs.
