What does a form field default to if the type attribute is omitted from a form?

According to the HTML specification, if the type attribute is omitted from an element, its default state is "text". This means the browser will render a single-line plain text input field. This behavior ensures backward compatibility and provides a sensible default for form controls when a specific type is not declared. The same default applies if the type attribute is given an unknown or invalid value.

A. A date picker is rendered only when the type attribute is explicitly set to "date".

C. A slider control is rendered only when the type attribute is explicitly set to "range".

D. A numeric input field is rendered only when the type attribute is explicitly set to "number".
