Which of the following shows correct capitalization?

“welcome home, mr. holmes,” said mrs. hudson. “your rooms are as you left them.”

“welcome home, mr. holmes,” said mrs. hudson. “your rooms are as you left them.”

“welcome home, mr. holmes,” said mrs. hudson. “your rooms are as you left them.”

“welcome home, mr. holmes,” said mrs. hudson. “your rooms are as you left them.”

The correct answer is the last option: "Welcome home, Mr. Holmes," said Mrs. Hudson. "Your rooms are as you left them."

Explanation:

The last option is the correct answer because the position of the capital letters is correct. According to the rules of capitalization in English, names and titles of people must be capitalized, therefore, Mr. Holmes and Mrs. Hudson are written with a capital letter. The first word of a sentence should also be capitalized, in this case, the word Welcome. Finally, the first letter after a period should also be capitalized, in this case, the word Your.
