Which of the following is a true statement about the mapping?

The main idea is how a mapping defines its keys. In this case, the mapping uses single-letter keys: m, y, and n. These keys are shorthand representatives for the components being tracked (for example, month, year, and now). That makes the statement about the actual keys being m, y, and n the correct one, because it accurately describes how the mapping is structured. The other statements misstate the structure: they either treat the keys as full words rather than single letters, or introduce a key like "time" that doesn’t appear in this mapping, or assign a value in a way that doesn’t match how the keys are used. So the key takeaway is that the mapping’s keys are the letters m, y, and n.
