Answer

Correct answer: a) Astringents

Astringents precipitate surface proteins on the skin/mucosa without penetrating cells, forming a protective layer that mechanically toughens the surface and reduces exudation/secretion — used for weeping skin lesions and minor bleeding. Emollients soften/soothe skin without this protein-precipitating action, adsorbents bind substances onto their surface (e.g. activated charcoal), and demulcents form a soothing protective film over irritated mucous membranes without precipitating protein.
