Explanation
In India, a District Judge is under the control of the High Court of the respective state in which the district falls. Therefore, option B is correct.
The High Court has administrative and supervisory control over all the district courts and judges within its jurisdiction. The District Judge is responsible for the administration of justice in the district, and the High Court monitors their performance, provides guidance, and exercises disciplinary control.
The Supreme Court and the Governor do not have direct control over District Judges, as their jurisdiction is limited to higher courts and overall state administration, respectively.
