Unique IDs are utilized in programming, especially within the context of HTML and JavaScript, to identify individual elements on a web page uniquely. When considering the statement regarding event handlers, it's important to note that while unique IDs are often associated with elements that respond to events, having an event handler is not a prerequisite for an ID itself.

IDs serve primarily to allow reference to those interface elements in the code, enabling developers to manipulate them in various ways, not solely through event handling. Since IDs themselves do not inherently require an event handler, this makes the statement inaccurate.

The other statements hold true: IDs indeed provide a way to reference interface elements programmatically, it's beneficial for IDs to be descriptive for clarity, and multiple event handler calls can indeed reference the same ID to manage events across different scenarios for that specific element. This understanding highlights the flexibility and functionality of IDs in programming contexts.
