To arrive at the answer, let's analyze the question and the answer choices provided.

The question states that after a serialized drama peaks, its ratings usually fall as infrequent viewers perceive themselves to be further behind the story. We need to choose the word that fits best in the blank space.

A. Allocation: This word refers to the act of distributing or assigning something, such as resources. It does not accurately describe the situation described in the question.

B. Acrobat: This word refers to a performer skilled in gymnastics or balancing acts. It does not relate to the context of the question.
