Courts of general jurisdiction typically have a judge and jury (answer A).
As their name implies, courts of general jurisdiction tend to address many different varieties of cases, both civil and criminal. For example, felonies, serious misdemeanors, breaches of contract, and child custody cases will all be heard in the general jurisdiction court.
The variety of potential cases means that general jurisdiction courts should be able to handle most types of trials. Depending on the situation, a jury, a judge, or a panel of judges may become necessary.
However, judicial panels are usually only employed for high-profile cases that move into a state or federal court. As such, they are typically not used in small general jurisdiction courts, and only a judge and a jury are required.
