The correct option is C Four Quarters
In Option a, adding three halves gives 12 + 12 + 12 = 1+1+12 = 32.
This is not equal to one.
In option b, adding two quarters gives 14 + 14 = 1+14 = 24.
This is not equal to one.
In Option c, adding four quarters gives 14 + 14 + 14 + 14 = 1+1+1+14 = 44 = 1
Therefore, option c is correct.
