I usually place a mine on anyone that I happen to kill and I have found that 90 percent of the time if I place a mine on a body and they get revived by the medic that the mine will blow up. However there is a very small percentage of the times that the mine might not be placed the best and the enemy can escape it. I've had this happen with people I mine and I have had it happen with my own teammates escaping mines. If I can offer any advice it's to double check before placing a mine on an enemy body.
As for the C4 it is meant to be triggered by someone. So if you lay C4 on a body and it doesn't blow up when a medic drone comes along that is because whoever laid the C4 out didn't manually blow it up. Hope that helps.
