A developer has to allow third-party applications to access the content of the Experience Fragment...

When it comes to rendering the content of an Experience Fragment for third-party applications to access directly via a URL, and in a browser-friendly format, thetextselector is used. This selector causes AEM to render the Experience Fragment as plain text, which is typically what a third-party application would require if it needs to consume the content directly without any associated styling or scripts.

Option B,noCss, is not a standard selector for this purpose.

Option C,plain, is not the correct selector for rendering Experience Fragment content in AEM. Theplainselector might suggest a text/plain MIME type, but in AEM, the correct selector for retrieving the text content of an Experience Fragment istext.
