You are building a web application that will be used throughout the European Union; therefore, it has significant internationalization requirements. You have been tasked to create a custom tag that generates a message using the java.text.MessageFormat class.
The tag will take the resourceKey attribute and a variable number of argument attributes with the format, arg<N>. Here is an example use of this tag and its output:
< t:message resourceKey='diskFileMsg' arg0='MyDisk' arg1='1247' />
generates:
The disk "MyDisk" contains 1247 file(s).
Which Simple tag class definition accomplishes this goal of handling a variable number of tag attributes?

• A.public class MessageTag extends SimpleTagSupport
  implements VariableAttributes {
  private Map attributes = new HashMap();
  public void putAttribute(String name, Object value) {
  this.attributes.put(name, value);
  }
  // more tag handler methods
  }
• B.public class MessageTag extends SimpleTagSupport
  implements VariableAttributes {
  private Map attributes = new HashMap();
  public void setVariableAttribute(String uri,
  String name, Object value) {
  this.attributes.put(name, value);
  }
  // more tag handler methods
  }
• C.public class MessageTag extends SimpleTagSupport
  implements DynamicAttributes {
  private Map attributes = new HashMap();
  public void setDynamicAttribute(String uri, String name,
  Object value) {
  this.attributes.put(name, value);
  }
  // more tag handler methods
  }
• D.public class MessageTag extends SimpleTagSupport
  implements DynamicAttributes {
  private Map attributes = new HashMap();
  public void putAttribute(String name, Object value) {
  this.attributes.put(name, value);
  }
  // more tag handler methods
  }
• E.The Simple tag model does NOT support a variable number of attributes.
