Answer:
(d) Congress has not passed a budget in some years because it will not follow its own rules.
Explanation:
"Nearly four months into fiscal 2018, Congress has passed none of the dozen spending bills it’s theoretically supposed to enact every year. Instead, lawmakers are on their third stopgap measure, which keeps government operations funded until Jan. 19. Failure to enact full-year spending bills by that date – or, failing that, another short-term measure – would force big chunks of the federal government to shut down."
Budget resolutions pass to start the coming fiscal year on October 1st, not in January nor May.
"If Congress does not complete action on an appropriations bill before the start of the fiscal year on October 1, it must pass, and the President must sign, a continuing resolution (CR) to provide stopgap funding for affected agencies and discretionary programs. [...]
Separately from the limits established in the annual budget process, Congress operates under statutory deficit-control mechanisms that prevent tax and mandatory spending legislation from increasing the deficit and that constrain discretionary spending."
