Answer:
B. The chair of the department thinks that English majors need more history and philosophy courses.
Explanation:
The option that uses the correct capitalization is option B. This is because apart from the word "English", words like department, majors and philosophy are common words.
The word "English" is the only proper noun in the above sentence and that makes it correct to use capitalization in the word "English". It should be noted that capitalization can be only used when the word is a proper noun.
