Answer:
C.(I might be wrong, its just my thoughts, explanation listed below)
Step-by-step explanation:
A. Bribing would most likely be wrong because if the soldiers were bad enough to destroy everyone the way they did they would probably take the watch and then destroy Mikhail anyway, so option A is out.
B. Since there were a lot of soldiers with guns, even if Mikhail started running the soldiers could have gotten Mikhail from long range with guns so option B is out.
D. If the soldiers were bad enough to do what they were doing, they probably would not take pity, so option D is out.
So C. is the answer as playing dead would be easy, it would give cover from gun shots, and that nobody would see that Mikhail would not be dead as Mikhail would be under bodies.
