The correct answer is A. A current biography or book
Explanation:
A biography is a type of source that focuses on describing important events on the life of someone, similarly, books about people mainly focus on their lives, actions, achievement, etc. This type of sources differs from other such as atlas because this includes only maps, from trade journals because these focus on specific industries and from "The White Queen" because this is a novel based on Queen Elizabeth. Therefore, the best and only source from the options that contain information about specific people is a current biography or book.
