(c)

Actually, I think, it depends more on the temperature. High temperature helps nitrogen and oxygen in air to react with each other.

NB: In the above question, coal and wood, both are fossil fuels.

Moumita Sen Coal is a fossil fuel, wood is not. Petroleum is also a fossil fuel. So burning all kinds of fossil fuels at high temperature produces nitrogen oxides.

Sayan Sinha Dear Ma'am, Wood is not a fossil fuel. I was wrong. Thank you for correcting me.
