Answer:
C They often are about people who lead relatively ordinary lives and have not done anything famous.
Step-by-step explanation:
In the past, biographies and autobiographies were only written about important people, Kings, or noble men and rarely of the common man. However, in recent times, more autobiographies and biographies have been written about the commoner.
Therefore, some modern biographies and autobiographies are different from classic biographies and autobiographies in terms of content because they often are about people who lead relatively ordinary lives and have not done anything famous.
