N2 minimum percentage is
Correct Answer:
95%
Explanation:
Think of N2 as nitrogen gas purity. When a minimum percentage is specified, it means the gas must be at least that pure to be considered nitrogen for the intended use, such as creating an inert or blanketing atmosphere. If you only had 60% N2, the remaining 40% would bring in enough other gases (often including oxygen) to compromise the inert conditions. The options that imply more than 100% nitrogen aren’t physically possible, and ranges that are too low wouldn’t meet the standard for an effective inert environment. Therefore, the minimum acceptable nitrogen content is 95%.
