Correct answer: A — Secondary Raynaud's phenomenon
Secondary Raynaud's phenomenon is the single best answer because capillaroscopy can support secondary Raynaud's and systemic sclerosis-spectrum disease. The stem is testing diagnostic synthesis, not isolated recall, so the relevant clinical pattern and risk context determine the answer. Rheumatoid arthritis is less suitable because it fits a different clinical pattern or a different treatment threshold; Systemic lupus erythematosus, Psoriatic arthritis and Gout do not address the key discriminator in this vignette. Clinical pearl: in SCE-style rheumatology questions, autoantibodies, imaging and synovial fluid findings should be interpreted with the whole phenotype.
