Solution:

HTML Code :

<!DOCTYPE html><!-- Specifies the document type as HTML -->
<html><!-- Starts the HTML document -->
<head><!-- Contains metadata about the HTML document -->
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"><!-- Sets the character encoding for the document -->
<title>How to specify the relationship between the current document and the target URL</title><!-- Sets the title of the HTML page -->
</head>
<body><!-- Contains the visible content of the HTML document -->
<img src="https://www.w3resource.com/w3r_images/html-area-element.png" alt="area example " width="308" height="190" border="0" usemap="#Map"><!-- Displays an image with an associated image map -->
<map name="Map"><!-- Defines an image map with the name "Map" -->
<area shape="rect" coords="8,5,100,77" href="https://www.w3resource.com/mysql/mysql-tutorials.php" target="_blank" alt="mysql tutorial" rel="alternate"><!-- Defines a rectangular area linking to MySQL tutorial with a relationship attribute "alternate" -->
<area shape="circle" coords="155,93,59" href="https://www.w3resource.com/php/php-home.php" target="_blank" alt="php tutorial" rel="alternate"><!-- Defines a circular area linking to PHP tutorial with a relationship attribute "alternate" -->
<area shape="rect" coords="197,136,306,188" href="https://www.w3resource.com/sql/sql-tutorials.php" alt="sql tutorials" rel="alternate"><!-- Defines another rectangular area linking to SQL tutorials with a relationship attribute "alternate" -->
</map>
</body>
</html>

Explanation:

The <!DOCTYPE html> declaration specifies the document type and version of HTML.
The <html> element is the root element of the HTML document.
The <head> section contains metadata about the HTML document, such as character encoding and title.
The <meta> tag sets the character encoding of the document to ISO-8859-1.
The <title> tag sets the title of the HTML page.
The <body> element contains the visible content of the HTML document.
The <img> tag displays an image with the specified source, dimensions, and attributes, including an alternate text for accessibility, and an associated image map.
The <map> element defines an image map with the name "Map".
The <area> tags define clickable areas within the image map, each with a specific shape, coordinates, hyperlink, alternate text, and a relationship attribute "alternate" specifying the relationship between the current document and the target URL.
