The correct answer is A. Informal; words that are comical and fun
Explanation:
The audience refers to the group of people a text is addressed to and that varies according to the purpose, topic and level of education a text requires to be read. On the other hand, the purpose of a speech refers to the main goal the author want to achieve with the text, common goals include persuading, narrate, explain or entertain. These two elements (purpose and audience) are especially relevant because according to them the author decides the type of language that is more suitable to use including the level of formality and words, for example, the language used in an argumentative essay that aims at persuading experts in a subject differs from the one used for narrating a story to your friends.
Considering this, in the case of a text that has as an audience children and that aims at entertaining them, does not require complex, technical or formal language as they might not understand it but simple or informal language and words that are funny and comical in order to achieve the purpose which is to entertain them. Thus, in this case, the type of language and word choice that matches with the audience is "informal; words that are comical and fun".
