Q. Which of the following statements is incorrect regarding ethanol blending?

[A] It can reduce stubble burning

[B] It reduces the emission of nitrous oxide

[C] It reduces the emission of carbon dioxide

[D] Sugarcane is the cheapest source of ethanol

Answer: B
Notes:

By using the left-over residue from rice harvests to make ethanol, stubble burning will also reduce.

Ethanol burns completely emitting nil carbon dioxide. By using the left-over residue from rice harvests to make ethanol, stubble burning will also reduce. The 2G ethanol project inaugurated last week will reduce greenhouse gases equivalent to about three lakh tonnes of CO2 emissions per annum, which is the same as replacing almost 63,000 cars annually on our roads. However, it does not reduce the emission of another key pollutant — nitrous oxide.
