To determine which of the given inequalities is correct when n > 0, we need to evaluate each inequality.

Option A, -n > 0

Given n > 0

n × (-1) < 0 × (-1) (multiply both sides by -1)

-n < 0

Since we multiply by -1, we need to flip the inequality sign. This inequality is incorrect.

Option B, 2n < n

Given n > 0

n + n > 0 + n (add n to both sides)

2n > n

There is no need to flip the inequality sign because we only performed addition. So, this inequality is incorrect.
