Solution

The correct answer is Option 3

Key Points

• Statement A: ✅ True. The number of tags decreases in XML since users can define their own tags based on their needs. This flexibility allows XML to be extensible and customizable.
• Statement B: ❌ False. XML is not used for presentation purposes. It is a data description and storage format. Presentation is typically handled by technologies like HTML or XSLT when XML data is displayed.
• Statement C: ✅ True. XML is case-sensitive. For example, `` and `` would be treated as two distinct elements.
• Statement D: ✅ True. XML is dynamic in nature because it allows users to define their own custom tags and adapt the structure as needed.

Additional Information

• XML Overview: XML (Extensible Markup Language) is a markup language used to store, transport, and describe data. It is platform-independent and widely used in data exchange between systems.
• Flexibility: XML allows users to create their own tags, making it highly adaptable for various use cases like web services, configuration files, and more.
• Case Sensitivity: XML enforces strict case sensitivity, which means elements, attributes, and tags must be consistently used with the correct casing.
• Non-Presentation: XML is designed for data representation and not for visual presentation. Presentation is handled by other technologies.

Hence, the correct answer is: Option 3) A, C, D Only
