Yes, it must be (C). I would also be willing to bet that it is an LSAT CR
Just for clarification, the governor and state Legislature are not one in the same. From wikipedia:
"In the United States, the title governor refers to the chief executive of each state, not directly subordinate to the federal authorities, but the political and ceremonial head of the 'sovereign' state. The governor may also assume additional roles, such as the Commander-in-Chief of the State National Guard forces (when not federalized), and the ability to commute or pardon a criminal sentence. U.S. Governors serve four-year terms except those in New Hampshire and Vermont, who serve two-year terms.
In all states, the governor is directly elected, and in most cases has considerable practical powers (notable exceptions with very weak governorships include Texas), though this is moderated by the state legislature
and in some cases by other elected executive officials. They can veto state bills."
