In HTML link for e-mail can be created using which of the following?

Question

Accepted Answer

The correct option is (3): The fundamental way to create any hyperlink in HTML, including one for an email address, is by using the anchor tag, ``, along with its `href` (Hypertext Reference) attribute. To specifically create an email link, the value of the `href` attribute must begin with the `mailto:` protocol, immediately followed by the target email address, such as `"mailto:pqr@example.com"`. This is the standard, well-defined mechanism recognized by all web browsers, which instructs the client's browser to open the user's default email program and automatically fill in the recipient's address in the 'To' field, thereby facilitating direct communication. The incorrect option is (1): The structure `... ` is incorrect because `` is not a valid or standardized HTML tag used for creating hyperlinks. HTML dictates that all link creation must be handled by the anchor tag, ``. Furthermore, while the email address is present, this construction attempts to assign an attribute using an incorrect syntax directly on a non-existent tag, which would cause the link to fail or be rendered as plain text by the browser. The incorrect option is (2): This option, ` pqr@example.com ... `, fails for multiple reasons. Firstly, like option 1, it incorrectly uses the non-standard `` tag. Secondly, it introduces another invalid and undefined tag, ``, to enclose the email address. Valid HTML links do not rely on a combination of invented, nested tags; they rely entirely on the established structure of the `` tag and its `href` attribute containing the `mailto:` protocol. The incorrect option is (4): While this option correctly uses the anchor tag ``, it contains a critical typographical error: the `href` attribute is misspelled as `herf`. HTML attribute names are case-sensitive or must be exact depending on the context (like XHTML), and this misspelling would prevent the link from functioning properly in many environments. Additionally, it incorrectly wraps the email address within a non-standard `` tag inside the attribute value, further violating the required syntax for the `mailto:` protocol, which expects the email address to follow directly after `mailto:`.
