Concept:
The Gupta period witnessed major developments in Indian temple architecture.
Important characteristics included:
• structural temples,
• shikhara beginnings,
• carved doorways,
• and stone temple construction.
Many early Hindu temples belong to this age.
Step 1: Examining the Kailasanath temple of Kanchi.
\[
\text{Kailasanath temple of Kanchi}
\]
This temple belongs to the Pallava period, especially associated with Narasimhavarman II.
Thus:
\[
A \text{ is incorrect.}
\]
Step 2: Examining Dasavatara temple at Deogarh.
\[
\text{Dasavatara temple at Deogarh}
\]
This is one of the finest surviving Gupta temples dedicated to Vishnu.
Thus:
\[
B \text{ is correct.}
\]
Step 3: Examining the Siva temple of Bhumara.
\[
\text{Bhumara Temple}
\]
This temple belongs to the Gupta age and is important for early Nagara architecture.
Thus:
\[
C \text{ is correct.}
\]
Step 4: Examining the Parvati temple at Nachna Kuthara.
\[
\text{Parvati Temple at Nachna Kuthara}
\]
This temple is another important Gupta-period structure.
Thus:
\[
D \text{ is correct.}
\]
Step 5: Writing the correct combination.
Correct statements are:
\[
B, C \text{ and } D
\]
Hence:
\[
\boxed{(3)\ B, C \text{ and } D \text{ Only}}
\]
Step 6: Importance of Gupta architecture.
Gupta architecture became the foundation for later:
• Nagara style,
• temple sculptures,
• and classical Hindu temple planning.
It represents the formative stage of Indian temple architecture.
