Answer:
C) The order in which events happened
Explanation:
When a text is written in chronological order, the events described in it are arranged in the order they take place.
For example, if a scientific article tells about a certain historical period, it should be written in chronological order because that is the only way we will properly understand it. We wouldn't be able to properly connect events if the article first told about something that happened in 1700, then about something from 1600, and finally about something from 1750.
