The stress is highest at the bends of low-temperature pipelines; therefore, these areas are most prone to brittle fracture, and welding of support structures should not be carried out there. B. The stress is highest at the bends of low-temperature pipelines; therefore, these bends are most prone to brittle fracture, and welding support brackets can be used. C. The stress at the bends of low-temperature pipelines is not high; these bends are less prone to brittle fracture, allowing for the welding of support brackets. D. The stress at the bends of low-temperature pipelines is not high; these bends are less prone to brittle fracture, and it is not necessary to weld support brackets there. 1) All participants will receive a reward (usually 5 points for correct answers, 3 points for incorrect ones, 1 point for unhidden answers; additional points may be given to those who provide detailed discussions) ； 2) Please hide your replies by clicking: Hiding method ； 3) Please do not edit after replying ； 4) This question will be closed the next day or when a new daily question is released; 5) Answer: A
