Selected Answer: B
No, this does not meet the goal. Splitting the IoT DateTime column into separate Date and Time columns will not improve dataset performance or enable analysis by the hour and day of the year. Splitting the column only separates the date and time components, but it does not provide the necessary functionality to analyze events by the hour and day of the year.
