The reason the student is reading.
Explanation:
Reading is a comprehensive activity that requires the interest or purpose of the readers which could be many like for interest, pleasure, research, build vocabulary, etc. Thus, the effectiveness of the reading depends on the reason or purpose for which a student is reading as the more determined the purpose would be, there are likely to be more chances to the competence to read well. Hence, the reason to study defines its effectiveness. There is no affiliation to a student's reading to the parents as the enforcement can make them study but not develop their interest which would lead to loss of efficiency. The number of pages too seems irrelevant as it is not merely a task but an activity that requires attention and interest. The location may impact the mood but not that effective as compared to the purpose of reading. Thus, the third option is the answer.
