Stepwise refinement involves breaking a larger problem down into smaller, more manageable parts. Option C falls in line with this approach by breaking down the problem into two smaller tasks: reading the city name and calculating the distance. This allows for better organization and modularity of the code, making it easier to maintain and modify in the future. Option A only addresses one part of the problem and does not provide a clear algorithm or methodology for calculating distance. Option B only addresses the input of city names but does not provide any logic for calculating distance. Option D suggests the opposite flow of information and does not follow a logical progression.
