Explanation:

Both 1 and 2

The first statement is correct. Anaerobic conditions, which are common in waterlogged rice fields, facilitate the production and release of methane (CH4), a potent greenhouse gas. Rice paddies are a significant source of methane emissions globally.

The second statement is also correct. The use of nitrogen-based fertilizers in rice cultivation can lead to the emission of nitrous oxide (N2O) from the soil. Nitrous oxide is another powerful greenhouse gas, and its emission is a concern in agricultural practices that rely heavily on nitrogen fertilizers.

Therefore, both statements are correct and contribute to explaining how rice cultivation can impact global warming.
