Explanation:
You can set the bin size for numerical and time fields in Power BI Desktop.
Incorrect Answers:
D: To add week hierarchy you would need to create a separate date table using CALENDARAUTO and then add a column
using WEEKNUM to that table. You would also need to add columns using YEAR, FORMAT([Date],"mmmm" and a quarter
function using SWITCH. Then you could build a hierarchy manually using these columns. Binning would be easier and
quicker.
