How far is it to the bus stop?

The answer "About five minutes' walk" is appropriate as it provides a concise and specific indication of the distance to the bus stop. This response gives a clear timeframe that can be easily understood and visualized, allowing someone to estimate how long it would take them to reach the bus stop from their current location.

Using time as a measure of distance is common in conversational English, making this option relatable and practical. The estimate suggests that the bus stop is within a short walking distance, which efficiently communicates the idea of accessibility. The other options, while they could also refer to the distance, either lack the specificity of time or do not fit the same short walking context.
