Correct Answer: (d) Ornamental and multi-storied structures upon the gateways.
Solution:Gopuram is a monumental tower, usually, ornate at the entrance of any temple especially in southern India. This forms a prominent feature of Hindu temples of the Dravidian style. The gopuram's origin can be traced back to early structures of the Tamil kings Pallavas and by the twelfth century under the Pandya rulers. These gateways became a dominant feature of a temple's outer appearance, eventually overshadowing the inner sanctuary which became hidden from the view by the gopuram's enormous size.
