What would be a reason for this?

An Adobe Commerce developer added a new API method to search and retrieve a list of Posts for a custom Blog functionality.

This is the content of the module’s etc/webapi.xml file:

The new code has been deployed to production and the merchant is using https: //merchant.domain.com/swagger to review the new endpoint, but it is not visible in swagger.

What would be a reason for this?
A . Since the new endpoint is not anonymous, the merchant needs to enter a valid integration token in swagger in order to see the new method.
B . The webapi.xml file should be moved into the etc/webapi_rest/webapi.xml file.
C . The @return annotation is missing in the MyVendorBlogApiPost Repositoryinterfacec

Answer: B
