The correct answer is A. To inform readers about information relating to Queen Elizabeth
Step-by-step explanation:
The purpose of a text refers to the objective or purpose an author has for writing a text and that includes to persuade or convince, to entertain, to describe or create a mental image and to inform. In the case of informative texts, these are texts that aim at providing information about a situation, event, issue or topic.
This can be seen in the excerpt presented because the writer includes details such as "The members of the Parliament went forth immediately to proclaim the new queen" and "two principal places where it was then customary to proclaim the English sovereigns" that mainly provide information to the reader about the coronation of Queen Elizabeth rather than persuading the audience or describing the palace where the coronation takes place. Therefore, the purpose of this excerpt is "to inform readers about information relating to Queen Elizabeth".
