Explanation:

The district judge is the highest judicial authority in the district. He possesses original and appellate jurisdiction in both civil as well as criminal matters. In other words, the district judge is also the sessions judge. When he deals with civil cases, he is known as the district judge and when he hears the criminal cases, he is called as the sessions judge. The district judge exercises both judicial and administrative powers. He also has supervisory powers over all the subordinate courts in the district. Appeals against his orders and judgements lie to the High Court.Hence all the statements are correct.
