Final answer:
In web development, 'current' is frequently used to denote an active nested menu link, helping indicate which menu item is active in the navigation structure.
Step-by-step explanation:
In web design and development, when indicating that a menu item has an active nested menu link, developers commonly use certain class names to style the menu item accordingly. While naming conventions can vary based on the developer or the framework being used, option C) current is often chosen to indicate the active state of a menu item. This is because 'current' intuitively suggests that the particular menu link is the one being engaged with or displayed.
