The expression seems to be asking for the difference between 80° and 40°, which is 80° - 40° = 40°. However, none of the options match this calculation directly. Given the options, it's possible there was a misunderstanding in the question's presentation. Assuming the task might involve finding the supplementary angle to the difference (which would be a common type of question involving angles), the supplementary angle to 40° is 140°, which is also not listed. Without further context, such as whether these angles are part of a geometric figure or if there's a specific operation implied (like addition, subtraction, finding supplementary or complementary angles), the correct answer based on the provided options and the straightforward subtraction is not listed. If the operation was intended to be the sum of the angles, then 40° + 80° = 120°, which matches option C, suggesting a possible misinterpretation of the task. Please clarify the operation or the context of the question for a more accurate response.
