The following table shows CFC emissions (in million metric tons) from various sectors for an industry for a period of 5 years. Based on the table answer the question given below.

Which sector has recorded the maximum percentage growth in CFC emissions from 2015 to 2019?

The percentage growth in emissions from 2015 to 2019 for each sector can be calculated as:

​$$\text{Percentage Growth} = \frac{\text{Emissions in 2019} - \text{Emissions in 2015}}{\text{Emissions in 2015}} \times 100$$​​

Emissions in 2015 = 200 

Emissions in 2019 = 450

Percentage Growth: $$\frac{450 - 200}{200} \times 100 = \frac{250}{200} \times 100 = 125\%$$​​

Emissions in 2015 = 500

Emissions in 2019 = 800

Percentage Growth: $$\frac{800 - 500}{500} \times 100 = \frac{300}{500} \times 100 = 60\%$$​​

Emissions in 2015 = 80

Emissions in 2019 = 200

Percentage Growth: $$\frac{200 - 80}{80} \times 100 = \frac{120}{80} \times 100 = 150\%$$​​

Emissions in 2015 = 100

Emissions in 2019 = 180

Percentage Growth: $$\frac{180 - 100}{100} \times 100 = \frac{80}{100} \times 100 = 80\%$$ 

Thus, Foam Sector(150%) has maximum growth in CFC emission.
