What tag is used in a form to add a button option?

The button tag is specifically designed to create a clickable button within a form in HTML. It provides users with a way to submit the form or trigger a specific action defined by the developer, such as executing JavaScript when clicked. This tag allows for more customizable button behavior compared to other options, as it can contain text, images, or icons, and can be styled with CSS for various visual effects.

Additionally, the button tag can be enhanced with attributes, providing greater flexibility. For example, you can specify whether the button's behavior is to submit a form or not, based on its type attribute (e.g., type="submit" or type="button"). This versatility makes the button tag an essential element in creating interactive forms.

In contrast to the button tag, the input tag is a more general form element that can also create a button, but it’s primarily used for text input and other input types, making it less specific for button functions. The submit tag actually refers to an input button in HTML with a type of "submit." While functional, it is not as flexible and customizable as the button tag. The fieldset tag is used for grouping related elements within a form and does not serve to create any sort of button functionality
