Explanation:

🆕 New Concept Discovered: Toxicological Effects of Combustion Byproducts
Understanding how incomplete combustion produces harmful gases.

Step 1: Identify the key characteristics of the substance

The question asks for a substance that meets three specific criteria:

1. It is a gas.
2. It is a deadly component found in automobile exhaust.
3. It is present in high concentrations in tobacco smoke.

Step 2: Evaluate the given options

• a) nicotine: This is an addictive alkaloid liquid/chemical found in tobacco plants, not a primary toxic gas associated with automobile exhaust.
• b) tar: This is a thick, sticky dark liquid/solid residue produced by burning tobacco, not a gas.
• c) hydrogen cyanide: While highly toxic and present in trace amounts in tobacco smoke, it is not the primary deadly gas characteristically associated with standard automobile exhaust in high concentrations.
• d) carbon monoxide: This is a colorless, odorless, and highly toxic gas produced by the incomplete combustion of carbon-containing fuels (such as gasoline in car engines and tobacco in cigarettes). It binds strongly to hemoglobin in red blood cells, reducing oxygen delivery to the body.

Answer:

d) carbon monoxide
