Answer:
a. the case is being heard for the first time.
Step-by-step explanation:
Stan is a citizen of Iowa and Jalisco farm supply although they are a Texan company operate in Iowa so the matter under dispute took place in Iowa.
The state trial court has jurisdiction because this is the first hearing of the case and from all indications the matter under dispute was perpetrated in Iowa.
So the state trial court has original jurisdiction in the case unless proven otherwise during the hearing.
