The correct answer is B, 32-34.
Answer resolution: In the GroupOutput setting, when the output address is 32-35, the range of each address is 32 to 35, including 32, 33, 34, and 35. When simulating, the input decimal data is 7, and after conversion to binary, it is 111, indicating addresses 32, 33, 34. Therefore, option B, i.e. 32-34 addresses, is set to 1.
