What is the prefix used by standard VisualForce markup tags?

1. vf

2. apex

3. c

4. s

The correct answer is: apex

The correct prefix used by standard Visualforce markup tags is "vf." Visualforce is a framework that allows developers to build custom user interfaces in Salesforce, and it utilizes its own set of markup tags. The prefix "vf" is essential as it indicates that the tags are part of the Visualforce framework, differentiating them from other types of markup. For example, you might find tags like <vf:page> or <vf:inputText>, which are specifically components defined for use within Visualforce. In contrast, the prefix "apex" is used for Apex components, which are server-side scripting components in Salesforce, and not for standard Visualforce tags. The prefix "c" typically refers to custom components created by developers, while "s" is not recognized as a standard prefix within the context of Visualforce markup. Understanding the prefix system is crucial for properly implementing and utilizing Visualforce in Salesforce applications, as it helps to avoid confusion between standard and custom components.
