By the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, the possible range for the third side in this case is between 12 - 10 = 2 and 12 + 10 = 22.
Since the third side must be greater than 10 and less than 22, the correct answer from the choices provided is 15.
