Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 4 i.e. Usage
The fast climate change we are presently witnessing is the result of humans' (3) usage of oil, gas, and coal in their homes, industry, and transportation.
= Humans have been using oil, gas and coal for self and mass utilisation since ages which has caused the climate change that we face today. Although some people waste like spilling oil into the sea or misusing some of the fuels, these should be stopped altogether to save the planet. So, 'usage' fits correctly here.
Hence, Usage is the correct answer.
