The inequality \( N = 6 < -1 \) is not true, as 6 is not less than -1. It seems like there may be a confusion or a typo in your expression of N.
If you meant to compare N to another number instead, please clarify that, and I can help you solve it. However, based on the given numbers and the format, none of the provided answers directly relate to the inequality \( 6 < -1 \).
If you're looking to solve an inequality involving \( N \), please provide the correct inequality for further assistance!
