Choice A is a single value; it is not a range.

Choice C says the heights are greater than 44 and greater than 72 inches. That is equivalent to saying the height is greater than 72 inches. That is not true.

You will NEVER see a range of values presented in the form a < x > b or a > x < b.

Choice D says the heights are less than 44 inches and greater than 72 inches; that is self-contradictory and so is nonsense.

Choice B is the correct form for the answer. It says the heights are greater than or equal to 44 inches and less than or equal to 72 inches.

You will almost ALWAYS see a range of values shown this way. The same range could correctly be presented as 72 >= h >= 44; but you will rarely (if ever) see it shown that way.
