Explanation:

• Nitrous Oxide (N2O) as a greenhouse gas (GHG) is 300 times more potent than carbon dioxide (CO2). 
• Nitrous Oxide (N2O) has the third-highest concentration, after CO2 and methane (CH4), in Earth’s atmosphere among GHGs responsible for global warming. 
• N2O is also a threat to the ozone layer, for it accumulates in the atmosphere over a long period of time, just like CO2.
• It can live in the atmosphere for up to 125 years.
• Its global concentration levels have increased from 270 parts per billion (ppb) in 1750 to 331 ppb in 2018, a jump of 20%.

Hence both statements are correct.
