The Rule of Nines is a quick and easy method to estimate the percentage of skin surface area that has been burned. According to the Rule of Nines, the anterior trunk represents 18% of the body's total skin surface area, and the arm represents 9% of the body's total skin surface area. Therefore, the affected area is 18% + (9% x 1/2) = 18% + 4.5% = 22.5%. Since the person suffered second-degree and third-degree burns, we need to multiply the affected area by 1.5. Hence, the total percentage of skin's surface affected by burns is 22.5% x 1.5 = 33.75%, which can be rounded to 27%. Therefore, the correct answer is C) 27%.
