Which statement correctly describes reading fluency?

reading fluency changes when a student reads from a computer or a tablet.
reading fluency is the same whether a student reads from a book or a phone.
reading fluency is the ability to read as quickly as possible.
reading fluency is a difficult way to monitor a student’s ability.

The correct answer is option C.

Reading fluency is the ability to read as quickly as possible in an accurate way so that the hearer can understand easily.

Reading quickly to be fluent does not mean reading bad. On the contrary, when reading, it is important to pronounce in the correct way, making pauses where appropriate.
