Question

A. It reduces oxygen transport in the blood.
B. A related atmosphere statement, but it misses the process angle required here.
C. A misconception that belongs to a neighbouring Chemistry of the atmosphere objective.
D. A vague claim that does not connect Atmospheric pollutants from fuels to the specification point.

Answer

The correct option is It reduces oxygen transport in the blood.. For this process question, that option is correct because it matches Describe carbon monoxide as a toxic gas produced by incomplete combustion in Atmospheric pollutants from fuels.

Explanation

It reduces oxygen transport in the blood. is the correct answer for this AQA GCSE Chemistry atmosphere question. Check whether the option keeps the chemistry sequence in the correct direction. The learning objective is: Describe carbon monoxide as a toxic gas produced by incomplete combustion. In Common atmospheric pollutants and their sources, this means the explanation must use the subtopic Atmospheric pollutants from fuels and avoid drifting into a different gas, pollutant, climate, or early-atmosphere idea. Checkpoint 13: this page uses the process angle so students can practise one distinct reasoning route before moving to the next question.

Common mistake

Misunderstanding Carbon Monoxide Production

Students often confuse carbon monoxide production with complete combustion processes, thinking it is produced in all combustion reactions.

Emphasize that carbon monoxide is specifically produced by incomplete combustion, where there is insufficient oxygen for complete oxidation of the fuel.
