Explanation

Test conditions are the inputs and expected outputs of a test case, based on the requirements. To identify the test conditions from REQ2 and REQ3, we need to consider all the possible combinations of the categories of hours exposed to the sun (A, B, C) and the labels of sun intensity (low, medium, high, extreme). There are 12 such combinations in total. However, the three test cases given only cover 3 of them: A-low, C-medium, and A-low. Therefore, there are 9 test conditions that are not covered by the test cases. However, some of these test conditions are invalid or impossible, such as A-extreme or C-low, because the sun intensity is correlated with the hours exposed to the sun. Therefore, we need to exclude these invalid test conditions from the count. According to the Skin Cancer Foundation, the sun intensity is usually low before 10 a.m. and after 4 p.m., medium between 10 a.m. and 1 p.m., high between 1 p.m. and 4 p.m., and extreme between 10 a.m. and 4 p.m. in the summer or at high altitudes. Based on this information, we can assume that the valid test These six test conditions are not covered by the three test cases, so the answer is C. 6.
