A) Plants obtain minerals and nutrients from the soil.

B) Contaminants in lakes harm water, plants, and fish.

C) Smoke in air causes breathing difficulty in animals.

D) Water in a lake evaporates into the air on a sunny day.

The answer would be:

C. Smoke in air causes breathing difficulty in animals.

Read on if you want to know why:

When you talk about biosphere it is referring to the living organisms on Earth. Bio - means "life". When we talk about atmosphere on the other hand, we are referring to the air around us. Atmos - means "vaporous air" around us.

Using those as your clue, take the answer as an example of how to determine what spheres were interacting:

Smoke in air causes breathing difficulty in animals.

Air and animals (living organisms)

So in short we know that the atmosphere and biosphere are interacting in this scenario.
