1. The problem asks us to determine which inequalities among A, B, C, and D are true. 2. Evaluate each inequality: - A: $6.8 > 5.9$ is true because 6.8 is greater than 5.9. - B: $-2.5 < -1.9$ is true because -2.5 is less than -1.9 (more negative). - C: $-4.7 > 2.3$ is false because -4.7 is less than 2.3. - D: $3.5 < -7.1$ is false because 3.5 is greater than -7.1. 3. From the evaluations, only A and B are true. 4. Therefore, the correct answer is the option that includes A and B.
