Given that there are 6 runners at a competition. So it means n = 6.
It says 2 medals are awarded for first and second place. So it means r = 2.
Each medal is different, it means the order matters here. It is the case of Permutations, so we will use nPr formula.
Total number of ways = 6P2 = 6x5 = 30.
Hence, option B is correct, i.e. 30 ways.
