The correct answer is B. No relationship
Explanation
Relationship is a word that is used to refer to a connection between two ideas, words, facts, people, objects among others. According to the previous definition the word "sunny" and "book" do not have any relationship because while the first concept refers to a meteorological issue such as the state of the weather, the other concept refers to an object that is used to tell stories. Therefore, the correct answer is B. No relationship.
