Answer:
The correct option is A) Living things respond to their environment.
Explanation:
All living things tend to respond to the environment in some way or the other. When any change arises in the environment, it acts as a stimulus for the organism. A response is generated by the organism by detecting this stimulus. For example, the weather is an environmental condition. When the weather becomes unfavourable for birds, they fly o the south where the weather conditions are better so that they can protect themselves from the excessive cold weathers. Such practices allow organisms to survive on the Earth.
