How much has the amount of carbon dioxide in the atmosphere increase since 1750? a. 10% b. 30% c. 50% d. 40%

The correct answer is D 40%

Option (D)

Explanation:

Carbon dioxide is an important greenhouse gas. It is currently about 0.03% of CO₂ by volume and plays a significant role in controlling the earth's average temperature. A small increase in the amount of CO₂ can lead to an increase in global temperature.

Since 1750, the concentration of CO₂ has been constantly increasing due to the industrial revolution. The number of factories and industries has been set up, as a result of which a huge amount of toxic gases has been released into the atmosphere, thereby leading to the increase in the average earth's temperature.

Thus, according to the statistical data, CO₂ content has increased up to approximately 40%

Thus, the correct answer is option (D).
