D] None of the above.
There are two "threshholds" over which the effect of enhancers are reduced. For most Enhancers it's 70% and 100%.
It doesn't matter how you get over those thresholds, just that you are. Could be with 10 Training Enhancers, if you could slot that many in a single power, 3 SO's, or one of each type TO/DO/SO/HO/ect.
In your example the "total" increase to Damage would be redueced from 95% to about 91.25%
