100 players simultaneously decide whether to choose road A or road B. Each driver wishes to minimize the cost of travel. If a driver takes Road A, his cost is three times the number of cars on road A. If he chooses road B, he has to pay a toll of $20 plus he incurs a cost equal to the number of drivers choosing road B. A Nash equilibrium outcome is: (a) All 100 players choose A. (b) All 100 players choose B. (c) 64 choose B and 36 choose A. 1 (d) 30 choose A and 70 choose B
