Which Gupta-period temple is located at Deogarh (Uttar Pradesh)?

The Dashavatara Temple at Deogarh in Uttar Pradesh is a landmark early structural temple, usually dated to the Gupta period and dedicated to Vishnu. This question belongs to the Gupta and post-Gupta phase, a period reconstructed through inscriptions, coins, monuments, literary works, scientific texts and accounts of foreign travellers. The Gupta age is often described as a classical or golden age because of important achievements in Sanskrit literature, temple architecture, sculpture, astronomy and mathematics, but the label should not conceal regional diversity or social and political change. The generic alternatives point to other locations or lack the specific established name of the Deogarh monument. The stated answer is therefore correct because it satisfies the person, period, source and context together.
