The correct alternative is:

B. x > -4

"How so?"

1. First, you subtract "5" from both sides.

-5x+ 5 < 25 → -5x+ 5 -5 < 25 -5

2. Subtract.

- 5x + 5 -5 < 25 -5 → (-5 - -5) → -5x < 25 - 5

3. Subtract the numbers once again.

-5x < 25 - 5 → (25 - 5) → -5x < 20

4. Divide both sides by the same factor and flip the relation.

-5x < 20 → -5x/-5 > 20/-5

5. Cancel the terms.

-5x/-5 > 20/-5 → (-5x/-5) → x > 20/-5

6. Then, divide.

x > 20/-5 → (20/-5) → x > -4

I apologize if this is incorrect! I hope you have a lovely day! :)
