Q. Terms Anda, harmika, yasti, chhatri pertain to which of the following?
Answer: Parts of Buddhist stupas
Notes: The terms Anda, harmika, yasti, and chhatri are features of Buddhist stupas. A stupa is a burial mound that symbolizes the Buddha's burial mound. The terms are defined as follows:

• Anda:A hemispherical mound that symbolizes the mound of dirt used to cover Buddha's remains
• Harmika:A square railing that represents the Abode of the Gods
• Yasti:A mast that arises from the harmika
• Chhatri:An umbrella-like structure that shelters relics and is supported by a large central pillar

Stupas originated as simple semi-circular mounds of earth. They gradually evolved into more complex forms that combine round and square shapes.
