D. Work well at all Temperature ranges. They better do this. A few days ago the outside temperature where I live reached - 40. The summer can reach plus 30 C. That's a range of 70 degrees. They better work over this range.
Unfortunately B is also true. I think you are intended to pick B, but D is also true. Perhaps the question means a greater range than 70 degrees. If that is so, B is really your better answer.
