Answer:
C
Step-by-step explanation:
C is the correct answer because it represents exactly what the graph shows with the bold lines.
As you can see in the graph, there is no interception between 7 and 12. Therfore, the answer can't be B(because it represents the area between the two numbers).
A isn't the correct answer either because it represents a dot, which is obviously not the case here since there is no dot.
I can't explain why C isn't the right answer, but I hope that explanation that I gave is enough for you to understand ;)
