The correct answer is option 3, Guptas. The coins of the Gupta Empire reveal their love for music. The Guptas were known for their patronage of the arts, including music. Their coins often depict musicians playing various instruments, such as the veena, flute, and drums. These depictions on their coins indicate the importance they placed on music in their society. The Guptas believed in the promotion and preservation of the arts, and music played a significant role in their culture. The other options, such as Mauiyas, Nandas, and Cholas, do not have any specific association with music mentioned in the context.
