Heroin is obtained from

Indian hemp
Opium poppy
Tobacco

The correct answer is (b). Heroin is a semi-synthetic opioid derived from thebaine, an alkaloid found in the opium poppy. It is typically processed from morphine, a naturally occurring substance extracted from the seed pod of the opium poppy. Heroin can be injected, snorted, or smoked. It is a highly addictive drug that can cause serious health problems, including overdose, addiction, and death.

Indian hemp is a plant that is used to make marijuana. It is not a source of heroin.

Tobacco is a plant that is used to make cigarettes, cigars, and other tobacco products. It is not a source of heroin.

Arecanut is a seed that is used to make betel nut. It is not a source of heroin.
