Concept:
Several addictive drugs are derived from different plants.
Knowledge of their botanical source is important in understanding narcotic and hallucinogenic substances.
Step 1: Study Cannabis-derived products.
The plant Cannabis sativa yields products such as:
• Bhang
• Ganja
• Charas
• Hashish
These contain cannabinoids, particularly tetrahydrocannabinol (THC).
Step 2: Analyze other options.
Morphine is obtained from opium poppy (Papaver somniferum).
Heroin is a derivative of morphine.
Cocaine is obtained from leaves of coca plant (Erythroxylum coca).
Therefore these options are incorrect.
Step 3: Final conclusion.
The drug obtained from Cannabis is:
\[
\boxed{\text{Hashish}}
\]
Hence option (C) is correct.
