Chips manufacturers usually flush bags of chips with which of the following gas?

Nitrogen

The correct answer is option 3. Nitrogen

Chips manufacturers usually flush bags of chips with Nitrogen gas. Nitrogen gas is commonly used in food packaging to displace oxygen. By replacing the air inside the packaging with nitrogen, manufacturers can help preserve the freshness and prevent oxidation of the chips, which can lead to staleness and rancidity. Additionally, nitrogen helps maintain the crispiness and texture of the chips during storage by reducing the presence of moisture. Therefore, the correct answer is Nitrogen.
