How can the address "The Empire State Building 20 W 34th St New York, NY 10001" be correctly formatted in HTML?

The correct formatting of the address "The Empire State Building 20 W 34th St New York, NY 10001" in HTML is achieved by using the line break element, <br>, to separate different components of the address for better readability.

In option A, each component of the address is placed on a new line, clearly delineating the building name, street address, city, and zip code. This improves the presentation for users reading the address on a webpage, making it easier to parse and understand.

The other options do not provide the same clarity. In option B, the address is presented in a single line, which could make it difficult for users to easily distinguish between the different parts of the address. Option C incorrectly uses the <b> tag, which is intended for bold text rather than structure, and it also contains an improper closing tag. Option D misuses the <div> element, which is intended for larger blocks of content, not for line breaks, and it also contains incorrect closing tags.

Properly formatted HTML for addresses enhances user experience and accessibility, making option A the most effective choice.
