  3. 2030

  4. 2040
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
With the increased rate of population, the demand for natural energy resources has also increased over a period of time. 
Petroleum is a non-renewable source of energy because it takes thousands of years for the crude oil to be formed in the earth. 
The increasing demand for the use of petroleum is much faster than the rate at which petroleum is produced. 
So, the petroleum in the earth's reservoir is estimated to be finished in next few years by the end of 2030 as per the reports of IEA (International Energy Agency).
So, the correct answer is '2030'
