Answer

Brief Explanations:

The 1952 London "killer - fog" was mainly due to the large - scale burning of coal for heating in winter. The emissions from millions of coal fires combined with stagnant air conditions, causing toxic fumes to accumulate in the air. This led to severe air pollution and health problems for the population. Option a is incorrect as it was mainly an air - pollution issue rather than water - supply contamination causing deaths. Option c about poor city design and house ventilation is not the main cause. Option d about forest and wildfire soot is not the main contributor.

Answer:

B. Millions of coal fires and stagnant air caused toxic fumes to build up in the air.
