What is the solution of the inequality x < 5?

The solution to an inequality is a range of values that satisfy the given inequality. In this case, the inequality is x < 5, which means all values that are less than 5. Option A (x ≥ 5) is incorrect because it includes values that are equal to 5, which do not satisfy the given inequality. Option C (x > 5) is also incorrect because it includes values greater than 5, which are not part of the solution. Option D (x ↓ 5) is not a valid option for representing a range of values. Therefore, the only correct solution is option B (x ≤ 5).
