https://docs.oracle.com/database/121/ADMQS/GUID-E6784230-0A0C-443D-8537-36FFA08A7E75.htm#ADMQS12039 In a text initialization parameter file, if you omit the line for MEMORY_MAX_TARGET and include a value for MEMORY_TARGET, the database automatically sets MEMORY_MAX_TARGET to the value of MEMORY_TARGET. If you omit the line for MEMORY_TARGET and include a value for MEMORY_MAX_TARGET, the MEMORY_TARGET parameter defaults to zero. After startup, you can then dynamically change MEMORY_TARGET to a nonzero value, provided that it does not exceed the value of MEMORY_MAX_TARGET.

With MEMORY_TARGET set, the SGA_TARGET setting becomes the minimum size of the SGA and the PGA_AGGREGATE_TARGET setting becomes the minimum size of the instance PGA.

I agree with the answer: A and D: A: if you omit the line for MEMORY_MAX_TARGET and include a value for MEMORY_TARGET, then the database automatically sets MEMORY_MAX_TARGET to the value of MEMORY_TARGET. https://docs.oracle.com/database/121/ADMIN/memory.htm#ADMIN11200
