Explanation:

Songs went from being one part to multiple parts – this is not the right answer. This is not what monophonic and polyphonic music means.

Songs went from being performed by one person to many people – this is the right answer. Monophonic songs are sung in one voice and it is only one melody. Polyphonic means there are more voices at the same time or that more melodies are going simultaneously. This Renaissance development to polyphonic changed music a lot compared to the Middle Ages. Many of Renaissance songs were composed as polyphonic compositions for masses sang in Latin in churches.

Songs went from being classical in nature to more electronic – this is not the right answer. This is not the meaning of monophonic and polyphonic, and also there was no electronic music in Renaissance.

There is no difference between monophonic and polyphonic music – this is not the correct answer. There is a difference between monophonic and polyphonic.
