Which entity may likely decide matters in a civil dispute?

A specialized court with subject matter jurisdiction is the correct choice because it refers to a court that has the authority to hear cases related to specific areas of law, such as family law, bankruptcy, or tax law. These courts are designed to handle civil disputes more effectively due to their focused expertise and established procedures. For example, a family court specializes in matters like divorce and child custody, ensuring that cases are adjudicated by judges who understand the complexities of these issues.

In contrast, the other options do not align with the typical judicial process for resolving civil disputes. The President of the United States does not have a role in adjudicating civil matters, as this function is reserved for the judicial branch. A jury of peers typically assists in determining the facts of a case in a trial setting, but it does so under the guidance of a judge who oversees the proceedings. The Supreme Court, while it may adjudicate civil cases, functions primarily as an appeals court and does not directly decide most civil matters, which are usually handled at lower levels of the judiciary. Thus, option B accurately reflects the entity responsible for deciding civil disputes in a specialized manner.
