Final Answer:
The control that displays a list of values and allows users to select one from the list is the Dropdown. The correct option is 2) Dropdown because a Dropdown control is specifically designed to display a list of values and allows users to select one option from that list.
Step-by-step explanation:
The Dropdown control serves as a user interface element that presents a list of options, typically in a vertically expanding menu format. Users can select one value from the displayed list. This functionality makes Dropdowns particularly useful in scenarios where there's a need to conserve space while providing a clear and concise selection mechanism.
Unlike checkboxes that allow multiple selections or radio buttons that limit users to one choice within a set, Dropdowns are designed for compactly presenting a range of options while enabling users to make a single, distinct selection.
In the realm of web and software development, the Dropdown control is implemented through HTML select elements or similar constructs in other programming languages. The list of values, often referred to as options, can be predefined or dynamically generated based on data sources.
Users interact with the Dropdown by clicking or tapping on it, causing the list of options to expand, and they can then choose the desired value. This makes Dropdowns an efficient and user-friendly choice when dealing with scenarios that involve selecting one option from a list without cluttering the interface.
To sum up, the Dropdown control stands out as the appropriate choice for displaying a list of values and facilitating user selection in a streamlined manner. Its functionality aligns with the specific requirements outlined in the question, distinguishing it from alternative controls like checkboxes, radio buttons, or text boxes, each serving distinct purposes in user interface design.
