Which of the following is appropriate option to display on web page 'We Love BSF Very Much' with a tool tip (full form) for the word 'BSF' ?

Question

Accepted Answer

The correct option is (3): This is the appropriate option because it uses the correct, semantic, and standard HTML5 element for marking up an abbreviation or acronym. The **\** tag semantically indicates that the enclosed text ("BSF") is an abbreviation. Crucially, the **title** attribute is the universally recognized HTML mechanism for providing supplementary information about an element. When a user hovers their mouse cursor over the abbreviated text "BSF," the browser automatically displays the text provided in the **title** attribute, which is the full form "Border Security Force," as a tooltip. This combination ensures cross-browser compatibility, semantic correctness, and accessibility, making it the proper solution for the requirement. The incorrect option is (1): The tag **\** is not a valid or defined tag within the HTML standard (up to HTML5). HTML elements must conform to the specifications set by the W3C (World Wide Web Consortium) to ensure proper rendering across different web browsers. Since **\** is non-standard, a web browser would likely ignore this tag entirely or treat it as an inline element with no special semantic or display function, failing to generate the required tooltip. Furthermore, the syntax of the attribute usage is also incorrect according to HTML rules. The incorrect option is (2): While the abbreviation itself is used as the tag name, **\** is not a standard, recognized HTML tag. Even if a custom tag were to be used, the correct way to attach a tooltip is still by employing the standard **title** attribute, not by attempting to define an attribute name that matches the tag's content. HTML's design dictates that the `title` attribute is solely responsible for this generic tooltip behavior. This option incorrectly attempts to invent both a tag and an attribute functionality. The incorrect option is (4): The element **\** is not a predefined HTML element and therefore is non-standard. Additionally, the syntax in the option is fundamentally flawed, as it attempts to assign the value ("Border Security Force") without specifying an attribute name (e.g., `title=`). HTML attribute values must always be associated with a named attribute. Browsers will treat this malformed markup as an error, and the desired tooltip effect will not be achieved.
