Correct answer: B — Psoriasis

Psoriasis is a chronic immune-mediated skin disorder with the classic Auspitz sign — removal of silvery scale from a plaque reveals punctate bleeding points (dilated capillaries in elongated dermal papillae). Oral psoriasis is debated but geographic tongue (benign migratory glossitis) and fissured tongue are strongly associated with psoriasis. Some studies report psoriatic-like changes of the oral mucosa resembling geographic tongue in up to 10% of psoriasis patients.
