Answer:
Choice C
Explanation:
We first have to find the sum of the students.
85 + 240 + 125 + 50 = 500
Next, we have to find the percentage of each group of students for each group.
Users of Tweeter = 85 (17%)
Users of VidTok = 240 (48%)
Users of Headbook = 125 (25%)
Users of Picturegram = 50 (10%)
Therefore C is the answer
