Answer:
d, all states, as no state requires at least two members to create an LLC
Step-by-step explanation:
The requisite of two members to create an LLC was removed from all states in the USA. Now, all states allow a single-member LLC. Massachussets was the last one to eliminate that requisite in 2003.
Maybe this change in laws was because owners cheated on that requisite by placing as the two members (owners) a man and his wife, or a woman and her husband, or some other person (in direct relation with the owner) which was just placing the name but the company actually belonged to only one member.
