Answer:
C). Circle Graph
Explanation:
As per the question, a 'circle graph' would be most adequate to display that the majority of the teenagers prefer to do their study and homework in their bedrooms. A circle graph or pie-chart represents the data in a visually appealing manner using colors to display various proportions of the data that makes it easy to understand for the readers. Thus, more than half of the circle filled with the same color will clearly hint that most of the teenagers love doing their studies in their bedroom. Thus, option C is the correct answer.
