The correct option is C nicotine
Tobacco leaves have been used by human beings for smoking, chewing or as snuff, from a long period of time. The smoke produced from burning tobacco contains over 4000 different chemical compounds including nicotine, carbon monoxide, carcinogens (compounds which can cause cancer), etc.
Nicotine is the major stimulating and highly addictive component of all tobacco products. Nicotine stimulates the nervous system by triggering the release of the neurotransmitters such as dopamine, which gives a good feeling or relaxing sensation. This stimulation is a major cause of nicotine addiction.
Nicotine also stimulates the release of endorphins and this creates a feeling of euphoria and pleasure in an individual when the individual puffs a cigarette and thus builds up the addiction.
Carbon monoxide gas has a high affinity for the haemoglobin present in our red blood cells. Upon inhalation, it readily binds with haemoglobin to form a stable compound named carboxyhemoglobin. This compound does not readily dissociate unlike oxyhaemoglobin (formed when oxygen combines with haemoglobin) or carbamino haemoglobin (formed when carbon dioxide combines with haemoglobin). Thus haemoglobin molecules are not available for the transport of oxygen and this leads to oxygen deficiency in the tissues. This is not a compound found in tobacco but a gas formed due to incomplete burning of tobacco, thus it cannot be considered as a component for addiction.
Lysergic acid diethylamide (LSD) is a hallucinogen. It creates hallucinations (seeing things which are not actually present at the time), a sense of euphoria, increased energy, a floating sensation, etc when taken into the body. It is not found in tobacco.
Morphine is a drug derived from opium (a drug derived from poppy seeds) that can act as a sedative and analgesic (painkiller). Morphine is absent in tobacco.
