When i saw my dad complete the game i remember him only having 2 choices, to destroy or to control the Reapers and i remember he chose to destroy, i remember the scene well as i remember seeing the shorts of the Illusive Man and Anderson and since i hadn't played the game i saw thinking did the Illusive Man try and control them already and got all scorched as a result of what i saw in the cutscene, i also remember the 2 choices was Blue and Red and had been wondering if the control option was Paragon and the destroy option was renegade.
Obviously my dad didn't have the Extended Ending DLC so when i got to the final choice i got the 2 choices he got, after listening to the Catalyst about what would happen to me i was thinking of control as i would probably end up like Madoka from Pellua Magi Madoka Magica, however then the Catalyst game me a third option to merge Synthetic and Organic, the Synthesis Choice.
Now i am unsure what decisions my dad made up to Mass Effect 3 so i am wondering if the Synthesis Choice was added because i have the Extended Ending DLC or if i had done something throughout the Mass Effect Trilogy which allowed it and if so what was it.

Synthesis was in the game originally. In my particular case, I had been playing all night right after it came out, trying to finish the game before I had to leave town, and didn't really understand that you could walk to the left, right, or ahead; and just walked straight ahead and chose it "by accident".
However, there is a minimum EMS required to make that choice available: according to that site, 2800. Dunno if that number was adjusted with the Extended Ending.
