Final answer:
The sentence with correct capitalization is 'Tanya asked Mayor Hsu to support our request for a skateboard park'. Titles before names and last names should always be capitalized.
Step-by-step explanation:
The correct sentence that uses proper capitalization is A. Tanya asked Mayor Hsu to support our request for a skateboard park. In this sentence, 'Mayor' is capitalized because it is part of a proper noun when used directly with a name, and 'Hsu' is capitalized as it is the last name of the person being addressed. When it comes to capitalization, it is important to recognize titles that precede names should be capitalized as well as the names themselves.
