The regions of the atmosphere, where clouds form and where we live, respectively, are:
  1. (A)Troposphere and Stratosphere
  2. (B)Troposphere and Troposphere✓ Correct
  3. (C)Stratosphere and Stratosphere
  4. (D)Stratosphere and Troposphere

Answer: (B)

Solution

Both cloud formation and human habitation belong to the troposphere, the lowest layer running from the surface up to about to km. It holds most of the atmosphere's water vapour, which is what makes clouds and weather possible. The stratosphere sits above it and carries the ozone layer, but it is neither where we live nor where ordinary clouds form.
