You set the value of the SGA_TARGET initialization parameter to 1G to enable Oracle to automatically resize most of the memory components according to the current workload in the database. You issue the following statement：   SQL> SELECT name， value， isdefault  2 FROM v$parameter   3 WHERE name LIKE ’%size%’；   The output of this statement displays that the DB_CACHE_SIZE， SHARED_POOL_SIZE，  LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters contain a zero value.  What does this imply？（）

• A、 The SGA_TARGET initialization parameter cannot be set to a value less than 1G
• B、 The SGA_TARGET initialization parameter cannot be set to a value greater than 1G
• C、 The Memory Advisor of the Oracle Enterprise Manager 10g cannot be used to obtain advice on the important memory components of the SGA
• D、 The values of the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters cannot be set manually.
• E、 No minimum limits are imposed on the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and  JAVA_POOL_SIZE initialization parameters.
• F、 The Automatic Shared Memory Management feature cannot be disabled unless you specify values for the  DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters in the initialization parameter file.
