D is the best answer. The author asserts that the writers in question “display a poor grasp of what intuition is” (lines 21-22). The next paragraph presents a view that, according to the author of the passage, characterizes intuition more accurately than the writers on management do. Isenberg’s research is specifically described as showing the ways in which managers use intuition (lines 28-30). Therefore, what Isenberg correctly comprehends, and the writers in question misunderstand, is how managers use intuition, as this choice states.
