The artistic styles of ancient Assam show influences from:

Gupta art
Pala art
Post-Gupta traditions
All of the above

The correct answer is: d) All of the above.

Gupta art is a style of Indian art that flourished during the Gupta Empire (c. 320–550 CE). It is characterized by its use of line, form, and color, as well as its depiction of religious and secular themes. Pala art is a style of Indian art that flourished during the Pala Empire (c. 750–1200 CE). It is characterized by its use of gold and silver, as well as its depiction of Buddhist themes. Post-Gupta traditions are a group of Indian art styles that flourished after the Gupta Empire. They are characterized by their diversity and their use of local materials and techniques.

The artistic styles of ancient Assam show influences from all of the above. This is evident in the region’s surviving temples, sculptures, and paintings. For example, the temples of Assam often feature Gupta-style architectural elements, such as pillars and arches. The sculptures of Assam often depict Pala-style figures, such as Buddhas and bodhisattvas. And the paintings of Assam often reflect Post-Gupta traditions, such as the use of bright colors and bold patterns.

The influences of Gupta, Pala, and Post-Gupta art on the artistic styles of ancient Assam are a testament to the region’s rich cultural heritage.
