The pattern displayed in the table is a clear indication of seasonality - a repeated pattern over time. There is no trend, positive or negative, as the values do not show a consistent increase or decrease over time. Additionally, there is no evidence of randomness in the values. Therefore, the only component present in this time series is seasonality, making choice C the best answer.
