"Teenagers who are tired are often tardy or fall asleep in class." is the answer.

The correct answer is the following: option A. The evidence that best supports Manjit's argumentative essay is the one that states that teenagers who are tired are often tardy or fall asleep in class. This is the only statement out of all the ones provided that supports Manjit's argument that high school should not start classes before 9.00 am. By stating that the students that are tired either get late to school or fall asleep during classes, Manjit is giving a valid reason on why school should begin later.
