Explanation:

The Amaravati school of art developed in the lower valleys of the Krishna and the Godavari. Nagarjunakonda, Amaravati, Ghantasala, etc., were the main centres of this art. A group of women enjoying their bath, depiction of the story of King Udayana and his queens, and the taming of an elephant by the Buddha are some of the memorable works of this school.

The general features of Amaravati art include (i) use of white marble, (ii) long legs and slender frames, (ill) human beings as central characters, and (iv) prominence of kings, princes and palaces.

Other two options are related to Gandhara school of art.
