Answer:
C. 50 visitors
Step-by-step explanation:
I got this answer by looking which amount of visitors seems equal to the graph. Camping is obviously the biggest, so it went with D, around 75 visitors. The next biggest looked like hiking, so that would do with C, 50 visitors. The third biggest ( swimming ) was 40 visitors, and the smallest section, fishing, went with A, 25 visitors. I hope this helped! :)
