Can a valid selector identify different elements on the screen simultaneously?

A valid selector primarily identifies a single element on the screen at a time, which aligns with the characteristics of most selector types commonly used in RPA frameworks. Selectors are typically designed to locate and interact with a specific element based on its attributes, such as ID, class, or position in the DOM structure. When a selector is applied, it returns a unique reference to that one element, allowing automation tools to perform actions precisely.

While there are scenarios and advanced techniques in which selectors can be configured to target multiple elements at once, this is not the standard behavior and often requires specific approaches or configurations. Therefore, the statement that a valid selector identifies one element only accurately reflects the conventional use and behavior of selectors in RPA development.

The other options explore different interpretations that may suggest a broader or conditional capability of selectors, but the primary design of a selector is to interact with individual elements to ensure accuracy and reliability in automation tasks.
