Answer:
A). It focuses on one main character and one main plot event.
Explanation:
Formal language is exemplified as the language that employs a specific syntax and terminology that promotes a 'less personal' and 'more sophisticated and conventional' tone in order to reflect seriousness and formality of the message.
In the given excerpt, sentence 3 could be best be revised by 'option A' i.e. 'It focuses on one main character and one main plot event' as the use of words 'character and plot event' inculcates a formal syntax and avoids 'colloquialism'(reflected by 'one person, one important thing' in sentence 3). It offers a more formal and less personal tone to the statement. Thus, option A is the correct answer.
