Let's evaluate each inequality:

Choice A:
$-7 < -5$ This is correct because on the number line, $-7$ is to the left of $-5$, meaning $-7$ is less than $-5$.

Choice B:
$-7 < 0$ This is correct because $-7$ is to the left of $0$ on the number line, so $-7$ is less than $0$.

Choice C:
$7 > -7$ This is also correct because $7$ is to the right of $-7$ on the number line, meaning $7$ is greater than $-7$.

Correct answers:

• Choice A: $-7 < -5$
• Choice B: $-7 < 0$
• Choice C: $7 > -7$
