Which statement about a URL is true?

• A. A URL cannot have spaces
• B. A URL is always case-sensitive
• C. A URL is a type of email address
• D. A URL is used to store files on your computer

Answer: (A)

URLs are the addresses used to locate resources on the web. They must follow a specific syntax, and spaces are not allowed in a URL; if a space is needed, it’s encoded as %20, or the browser handles that encoding automatically. That’s why the statement about not having spaces is true.

Some quick context to keep in mind: a URL isn’t an email address, even though you can link to an email with a mailto: URL. And while a URL can refer to a local file using the file:// scheme, its primary role is to point to resources, not to store files on your computer. Also, the part after the domain can be case-sensitive on some servers, even though the domain portion is generally not case-sensitive, so the idea that a URL is always case-sensitive isn’t accurate.
