Option D. Being selected to go to Baltimore
Explanation:
Frederick Douglass was born a slave in February 1818 on the farm of Holmes Hillm, near Maryland, United States. At the age of 12 he was transferred to Baltimore to serve the brother of his previous owner. While there the wife of his new master taught him to read, for this reason Douglass this was the most extraordinary event of his life, to be selected to go to Baltimore since he had the opportunity to do something that the other slaves did not.
