Answer 2

Answer:

The ‘time interval’ means that it is the difference between two instants of time. The time of the first bell in the school defines a particular instant of time. It is not a difference between two instants of time. Thus, it is not a ‘time interval’.  

All other options like a day, a second or a school period describe a period of time. This period of time is called time interval.
