Correct answer: B — Bacterial vaginosis

Thin grey discharge with fishy odour and clue cells is typical of bacterial vaginosis. Candidiasis more often causes itch and thick white discharge. Genital herpes causes painful ulcers. Bartholin abscess causes a painful unilateral vulval swelling rather than diffuse malodorous discharge.
