Answer:
B). A single, continuing sound.
Step-by-step explanation:
From the given chart, the most likely meaning of the word 'monotone' would be 'a single unvaried pitch.' The prefix 'mono-' stands for 'single' while the root word 'tone' means 'sound or pitch.' Thus, the complete word implies 'a single uniform sound without any change in its pitch or intonation.' Thus, option B is the correct answer.
