Answer:
The answer is: B. He looked at me carefully and stated, "Don't worry because I'm here."
Explanation:
In British English it is frequent to use a capitalization in the first letter of the word after a colon, but only if it's a proper noun or an acronym as in American English but it also depends on one thing: if a sentence is being introduced, this is why the first option cannot be possible. The penultimate option doesn't have any mistakes either as Atlantic Ocean has to be capitalized in both words, for the word "ocean" belongs to that part of the proper name; the same with the last option: Central Park and New York are proper nouns and must be capitalized. So the second option shouldn't be capitalized, with the comma and then the quotation marks, for someone saying something, unless it was a proper noun.
