One column of numbers consists of 28, 42, and 14. when the digits of the numbers are added together, the result is 2 + 8 + 4 + 2 + 1 + 4 = 21, and when the digits of 21 are then added together, the end result is 2 + 1 = 3. if the same process is performed on the numbers in a second column, what can be concluded?

a. if the end result from the second column is also 3, then the sum of the numbers in the first column is not equal to the sum of the numbers in the second column.
b. if the end result from the second column is not 3, then the sum of the numbers in the first column is equal to the sum of the numbers in the second column.
c. if the end result from the second column is also 3, then the sum of the numbers in the first column is equal to the sum of the numbers in the second column.
d. if the end result from the second column is not 3, then the sum of the numbers in the first column is not equal to the sum of the numbers in the second column.
