What is a Visualforce expression?

A method for deleting records.
A set of literal values or variables resolved to a single value.
A type of component in a Visualforce page.
An expression that can only include method calls.

The correct answer is: A set of literal values or variables resolved to a single value.

A Visualforce expression is fundamentally a set of literal values or variables that are evaluated to produce a single value within a Visualforce page. This expression allows developers to dynamically display data and interact with Salesforce objects without needing to write extensive code. For example, when you include an expression like `{!Account.Name}` in a Visualforce page, it retrieves the name of the account record being referenced, enabling users to see real-time data as part of the page rendering. The correct understanding of a Visualforce expression not only involves how it simplifies data representation but also its integration with the Salesforce data model, which enhances the user interface. This facilitates an interactive experience where data can change based on user actions or events. Thus, identifying this fundamental aspect as a set of literal values or variables resolving to a single value captures the essence of what makes Visualforce expressions an essential tool in Salesforce development.
