The correct answer is A. Chronological order
Step-by-step explanation:
A biography is a type of non-fictional texts that includes information about the life of someone especially those details that are more important and are related to topics such as family, education, job, legacy, etc. Additionally, a biography always includes information from the date a person is born to the date the person died and because of this, all details are commonly organized following chronological order or pattern in which the details included go from the oldest date to the most recent one. Therefore, the structure of the biography is chronological order as details are presented by date rather than according to importance, cause, and effect or problem and solution.
