This question tests CCSS.L.4.3.c: differentiating between contexts calling for formal English and situations where informal discourse is appropriate. Students must match language formality to audience and purpose. Formal English is used in presentations, school writing, and communication with adults in authority - it uses complete sentences, proper grammar, polite phrases like 'Dear' and 'Sincerely,' and academic vocabulary. Informal English is used with friends and family in casual conversations - it includes contractions, casual greetings like 'Hey,' slang, abbreviations, and conversational tone. The key is matching your language to who you're talking to and why. In this scenario, Sofia is writing a letter to the principal, which is a formal context because it involves communicating with an adult in authority for the purpose of making a respectful request. Choice B is correct because it uses formal markers like 'Dear Principal Chen' and complete sentences with polite phrases, which is appropriate for an official school letter; the language shows respect for authority and matches the formal situation. Choice A represents a common error of wrong register by being too casual, which occurs when students think any language works everywhere; using 'Hey' and 'Thx!' in a letter to the principal is inappropriate because it sounds disrespectful and unprofessional for an authority figure.

Create anchor charts showing formal markers such as 'Dear' and polite phrases versus informal ones like 'Hey' and abbreviations; watch for using too casual language with adults, over-formalizing casual situations, mixing registers, or not recognizing audience matters; role-play different contexts to practice switching between formal and informal appropriately.
