The correct answer is: D. Mitathal
The seven notes of music have been mentioned in the inscription which has been found at Mitathal, a village in the Hisar district of Haryana. The inscription is dated to the 2nd century BCE and is written in the Brahmi script. It is a record of a gift made by a king to a temple. The inscription mentions the seven notes of music, which are:
- Sa
- Re
- Ga
- Ma
- Pa
- Dha
- Ni
The inscription is significant because it is the earliest known record of the seven notes of music in India. It also provides evidence of the existence of a musical tradition in India at a very early date.
The other options are incorrect because they are not places in Haryana where an inscription mentioning the seven notes of music has been found.
- Sudh is a village in the Kurukshetra district of Haryana.
- Agroha is a town in the Hisar district of Haryana.
- Rohtak is a city in the Rohtak district of Haryana.
