B) The mutation is beneficial and allows those who have it to reproduce more than average.
If the mutation is beneficial, it will become common in a population since the individual(s) that have this beneficial mutation will survive longer to produce more offspring that have this mutation. These offspring will also live longer and spread this mutation through the gene pool through reproduction.
