The correct option is Nagarjunkonda and Goli.
Explanation
The question addresses the stylistic evolution of the Vengi or Andhra School of Art, specifically tracing the transition from the Satavahana period (represented by Amaravati) to the succeeding Ikshvaku period (represented by Nagarjunkonda and Goli).
Detailed Analysis:
- Amaravati School (Satavahana Phase): The sculptures from the peak phase of Amaravati (2nd century CE) are characterized by intense dynamism, crowded compositions, and a sense of nervous energy. The figures often exhibit exaggerated movement and complex tribhanga (three-bent) postures.
- Nagarjunkonda and Goli (Ikshvaku Phase): These sites represent the continuation of the Amaravati tradition into the 3rd and 4th centuries CE under the Ikshvaku dynasty. While the artistic idiom remains similar, the sculptures exhibit a noticeable reduction in animated movement. The figures appear taller, more slender, and the compositions are less crowded and agitated compared to the frenetic energy of the earlier Amaravati reliefs.
Key Takeaway: The later phase of the Andhra School at Nagarjunkonda and Goli is distinguished from the Amaravati School by its elongated figures and a marked decrease in dynamic movement and compositional crowding.
