Correct answer: A — Select by integrating the active disease domains, associated conditions and comorbidities, prior therapy, and the patient's goals and preferences

D is correct. BSR 2022 structures PsA treatment around the active domains — peripheral arthritis, axial disease, enthesitis, dactylitis and psoriasis — combined with associated conditions and comorbidities, previous drug exposure, and shared decision-making about patient goals. Here all three of peripheral synovitis, significant psoriasis and inflammatory bowel disease must shape the choice: IL-17 inhibition is avoided in active Crohn disease and used only cautiously with gastroenterology input when quiescent, whereas monoclonal TNF inhibitors or IL-12/23–IL-23 blockade cover both joints and gut/skin. A is wrong because skin severity is only one domain. B is false: classes differ materially by domain and by extra-articular disease. C ignores a comorbidity that changes drug safety. E inverts the hierarchy — cost may decide only between equally suitable, phenotype-appropriate options.
