To answer this question, you need to understand XSLT (Extensible Stylesheet Language Transformations) and how stylesheets are used in XSLT.
XSLT stylesheets can contain multiple templates to define how XML data should be transformed. These templates are used to match specific elements or patterns in the XML input and specify how they should be transformed or processed.
Therefore, the statement "XSLT stylesheets have a number of templates" is true. XSLT stylesheets commonly have multiple templates to handle various elements and patterns within the XML input.
So, the correct answer is A) TRUE. XSLT stylesheets can have a number of templates.
