You configure a data source with a non XA driver because your (non-Oracle) database does not provide XA drivers. The data source will sometimes participate in global transactions with an EJB, so as you configure the data source you select "Supports Global Transactions" and One-phase commit. Why is this configuration wrong? 

Answer options:

A. You must choose an XA driver when a data source participates in global transactions.
B. "One` Phase Commit" always returns "ready" during phase one of the two-phase commit process` so it is possible you will have heuristic errors in the database.
C. "One-Phase Commit" processes this data source last in the global transactions, if the EJB must go last, you cannot use this configuration.
D. "One-Phase Commit" only allows this data source to participate in global transaction, so you cannot have a global transaction that includes an EJB.

D
