The correct answer is: B. Gaya
Chatra is a district in the Indian state of Bihar. It is located in the south-central part of the state and is bordered by the districts of Hazaribagh to the north, Palamu to the east, Latehar to the south, and Gaya to the west. The district has a population of over 1.5 million people and its headquarters is the town of Chatra.
Gaya is a district in the Indian state of Bihar. It is located in the south-central part of the state and is bordered by the districts of Nalanda to the north, Jehanabad to the east, Aurangabad to the south, and Rohtas to the west. The district has a population of over 4.5 million people and its headquarters is the city of Gaya.
The other options are incorrect because they are not neighboring districts of Chatra. Jamui is located in the south-western part of Bihar, Arwal is located in the north-central part of Bihar, and Rohtas is located in the south-eastern part of Bihar.
