You have applications that have frequently executed queries， and produce small and static result sets.  You configure the sqlnet.ora file in the client machine to set a nonzero value for the OCI_RESULT_CACHE_MAX_SIZE parameter.  What is the purpose of this configuration？（）  

• A、 to avoid round trips to the server by enabling caching of query results in client memory
• B、 to improve performance by storing a copy of the data from the private SQL area of the PGA
• C、 to enhance the query performance by creating a cache in the client memory for sorting operations
• D、 to avoid the storing of query plans and results in the server by creating a cache in the client memory
