Where in a data table should units of measurement be shown?

a. in a separate column after the column of data values
b. in parentheses, in the title of the table
c. in the headings of columns that list the data values
d. in a note next to an asterisk, below the table

C. in the headings of columns that list the data values

Explanation:

Using a table software is good because you can use the cell input in calculations, but you can only do so if the content of the cell is only numbers, so the best place to put unitis (text) is in the headings of columns that list the data values.
