Why did the dark-colored variation of peppered moths become more common during the Industrial Revolution in Britain?

There was an influx of people into the cities during that time and they killed the white variation off since they didn't like them.

The pollution darkened the environment, which caused the dark-colored variation to become advantageous.

The pollution affected the lungs of the white variation moth more than the black variation and so more of the white died.

There was an increase of buildings built and the loss of habitat caused the white variation to go extinct.
