Examine these SQL statements which execute successfully:Which two statements are true after execution?

After the execution of the given SQL statements:

B. The primary key constraint will be enabled and IMMEDIATE. This is true. The last statement ENABLE CONSTRAINT emp_emp_no_pk; enables the primary key constraint immediately.

E. The foreign key constraint will be enabled and IMMEDIATE. This is correct as well. The foreign key constraint emp_mgr_fk was not explicitly disabled, so it remains enabled and in the immediate checking mode.

Options A, C, and D are incorrect:

A is incorrect because constraints are immediate by default; they are not deferred unless explicitly stated.

C is incorrect because the foreign key constraint emp_mgr_fk was never disabled with the given statements.

D is incorrect because there is no statement altering the foreign key constraint to a deferred state.
