All lawn maintenance businesses must pay the state a $200 annual fee for a license, with no other legal regulations.  ABC Yards Inc., fails to pay this fee.  Which is true in case of ABC Yards fails to acquire a license due to failure to pay the $200?

1. the lack of a license will not necessarily make a contract void
2. only executory contract by ABC will be voidable
3. all contract of ABC are voidable due to their failure to obey the regulation
4. the lack of a license makes the contracts void under contract laws

I think it is 3 or 4, but don't know which.
