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.
