  Choose the option that best evaluates the example:

  A. This is a valid example of two EJBs used as JAX-RS resources, one a root resource and the other a subresource.
  B. This is an invalid example, because EJBs that are to be used as JAX-RS subresources have to match the type of EJB of their "parent" resource.
  C. This is an invalid example, because singleton EJBs used as JAX-RS resources must explicitly state what locking strategy they will require.
  D. This is an invalid example, because the JAX-specification only allows root resource types to also be EJBs.
