Answer 2

Answer:

Formation of London smog takes place in (d) winter during morning time.

Explanation:

The London smog formation takes place mainly in the cold weather in the early morning but conditions appear to worsen after sunrise. It is because of the production of acidic aerosol.

It was the most severe kind of pollution that occurred due to smog containing sulphur in London. It was a mixture of fog, smoke and sulphur dioxide and hence known as the reducing smog.
