Explanation:

• Reactive arthritis: Usually follows an infection (e.g., gastrointestinal or urogenital). Skin manifestations are less likely to be a "butterfly" rash.
• Rheumatoid arthritis: Mainly causes joint inflammation (symmetrical polyarthritis). Skin manifestations like a "butterfly" rash are not typical.
• Psoriatic arthritis: Associated with psoriasis (scaly skin lesions). The "butterfly" rash is not a key feature.
• Systemic lupus erythematosus (SLE): Classic symptoms include a malar ("butterfly") rash (over the cheeks and nose), arthralgia (joint pain), and oral/nasal ulcers.

Answer:

D. systemic lupus erythematosus
