Choice D states that mental alertness is lower at night (for everybody) and ESPECIALLY for people not used to working at night - this implies that alertness is lower even for people WHO ARE USED TO WORKING AT NIGHT. Thus this choice exploits on the premise that upgrades are mentally taxing anyway, and on top of that the lower alertness at night would make the job more difficult. Choice D is definitively correct.
