A data scientist is working with a data set that covers a two-year period for a large number of machines. The data set contains: - Machine system ID numbers - Sensor measurement values - Daily time…

The correct answer is B. Line plot. Summing measurements across all machines for each day produces a time series, and a line plot is the standard way to visualize how that daily total evolves over the two-year period.
