Agricultural soils release nitrogen oxides into environment: Correct. Nitrous oxide (N\u2082O), a significant greenhouse gas, is released from agricultural soils through microbial processes (nitrification and denitrification), especially when nitrogen fertilizers are used. Other nitrogen oxides (like NO and NO\u2082) can also be released, though N\u2082O is the most significant from soil.<br \/>\n2. Cattle release ammonia into environment: Correct. Livestock, particularly cattle, excrete significant amounts of nitrogen in urine and feces. This nitrogen is converted to ammonia (NH\u2083) through microbial processes in manure and released into the atmosphere.<br \/>\n3. Poultry industry releases reactive nitrogen compounds into environment: Correct. Similar to cattle, poultry operations generate large amounts of nitrogen-rich manure, which leads to the release of ammonia and other reactive nitrogen compounds into the atmosphere. Poultry litter management is a major source of atmospheric ammonia.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nAll three statements describe significant anthropogenic sources of nitrogen compounds that impact the environment, contributing to air pollution, acid rain, eutrophication, and climate change (in the case of N\u2082O). Therefore, all three statements are correct. The options provided seem to have a typo with &#8220;4 only&#8221;; assuming option D represents &#8220;1, 2 and 3&#8221;, that is the correct choice.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Consider the following statements: 1.
