Reason : Psychedic drugs cause hallucination.

- If both assertion and reason are true and the reason is the correct explanation of the assertion.

### Psychedelic drugs changes one's mood, behaviour, thoughts, feeling and perceptions, without any true sensory stimulus. They cause hallucinations [a sense perception (sight, touch, sound, smell or taste) that has no basis in external stimulation]. LSD causes horrible dreams, emotional outbursts, hallucination, chronic psychosis and severe damage to the central nervous system. It also brings about chromosomal and foetal abnormalities. An LSD addict can be easily recognised from incoherence in writing and drawing.

### Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite (CuSO_{4} ,5H_{2}O), atacamite cuprite (Cu_{2}O), copper glance (Cu_{2}S) and malachite However, 80% of the world copper production comes from the ore of chalcopyrite (CuFeS_{2}). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. Iron is removed from chalcopyrite as
