Three persons A, B and C play a series of games with coins. In each game, they place some coins on the table and pick the coins in turns, starting with A, B and then C and the A again and so on. Each person in his turn has to pick either one or two coins. In any game, the number of coins with which the game starts is termed as the "primary count". In each game they get points according to the following conditions:
1. The person who picks up the last coin is the winner of that game and gets 2 points
2. The person whose turn is after the winner of that game gets 1 point.
3. The person whose turn is before the winner of that game gets no points.
Each person plays intelligently and tries to get the maximum number of points.
For which of the following primary counts will B get no points?
a) 15
b) 16
c) 17
d) none of these
