Which type of farming can be linked with methane emissions?
Answer and explanation
Correct answer: Paddy cultivation
Flooded paddy fields become low in oxygen. Microorganisms called methanogens decompose organic matter in these anaerobic conditions and produce methane, which can escape through the water and rice plants. Rice cultivation is therefore an important agricultural source of methane. The other listed crops are not characteristically associated with flooded methane-producing fields, so A is correct.
