Explanation:

The HTML document begins with a declaration of its type and version (<!DOCTYPE html>).
The <html> element encloses the entire HTML document.
The <head> section contains metadata about the document, such as character encoding and title.
The <meta charset="utf-8"> tag specifies the character encoding of the document as UTF-8.
The <title> tag sets the title of the document.
Inside the <body> section, there is a <form> element with the name "Fav_Sport".
The <label> element provides a label "Favorite Sports" for the form.
The <select> element defines a drop-down list with the name "favoritesports" and the ID "favoritesports".
Inside the <select> element, there is an <optgroup> element, which starts a group of related options labeled "Sports".
Inside the <optgroup>, there are <option> elements, each representing a different sport with its label attribute defining the display text.
The HTML document is properly closed with the </html> tag.
