Answer:
Option (C)
Step-by-step explanation:
From the circle graph attached,
14158428 students have been divided into the sectors of a circle which represent the most important problems for the high school teenagers.
Each sector corresponds the percent of different problem.
Red sector (22% of the total students) represents the most important problem of drugs.
14158428 students ≈ 14000000
22% ≈ 20%
Now 20% of 14000000 high school students = 14000000×![\frac{20}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B100%7D)
= 2800000
Therefore, Option (C) will be the answer.
