The correct option is D Hallucinogen
Mescaline is a hallucinogen obtained from the small, spineless cactus Peyote (Lophophora williamsi). It is also found in certain members of the Fabaceae (bean family). Users typically experience visual hallucinations and radically altered states of consciousness, often experienced as pleasurable and illuminating but occasionally is accompanied by feelings of anxiety or revulsion. Other effects include open and closed eye visualisations, euphoria, dream-like state, laughter and a psychedelic experience. So, the correct answer is option D.
