To answer this question, we need to understand the directives used to specify the HTTP response type.
Option A) - This option is incorrect because the "type" attribute is not used to specify the HTTP response type. It is used to specify the content type of the page being included.
Option B) - This option is incorrect because the "mimeType" attribute is not used to specify the HTTP response type. It is used to specify the MIME type of the page being included.
Option C) - This option is incorrect because the "language" attribute is not used to specify the HTTP response type. It is used to specify the scripting language used in the page.
Option D) - This option is correct because the "contentType" attribute is used to specify the HTTP response type. In this case, it specifies that the response will be of type "image/svg".
Therefore, the correct answer is D) . This option is correct because it uses the appropriate directive to specify the HTTP response type as "image/svg".
