The correct answer is A) to make the events easier to read.
A reason timelines are organized chronologically is "to make the events easier to read."
Another important reason why they are organized chronologically is to have the correct sequence of events and understand how the previous event affected the following event or many others. This way, historians, students, or people can get a better idea of how events were developed, the time frame, and the impact events had on other events that followed in line.
Timelines are good resources when studying events such as World Wars, battles, or news because they help us with the chronology of how events were developed form the beginning to the end.
