Concept:
Metal technology in India developed through different stages. Copper objects appeared very early, followed by bronze objects of the Harappan period, iron works, and later bronze sculptures of medieval India.
Step 1: Identify the earliest object.
Copper beads of Mehrgarh are among the earliest metal objects.
So, the first is:
\[
B = \text{Copper Beads of Mehrgarh}
\]
Step 2: Place Bronze Dancing Girl.
The Bronze Dancing Girl belongs to the Harappan civilization.
So, the second is:
\[
A = \text{Bronze Dancing Girl of Mohenjo-daro}
\]
Step 3: Place Iron Pillar of Delhi.
The Iron Pillar of Delhi belongs to a later ancient period and is famous for its rust-resistant quality.
So, the third is:
\[
E = \text{Iron Pillar of Delhi}
\]
Step 4: Place Bronze Nataraja.
Bronze Nataraja belongs to the Chola period.
So, the fourth is:
\[
C = \text{Bronze Nataraja Statue of Chola}
\]
Step 5: Place Iron Beams of Konark.
The Konark Sun Temple belongs to the medieval period.
So, the last is:
\[
D = \text{Iron Beams of Konark Sun Temple}
\]
Therefore, the correct sequence is:
\[
B \rightarrow A \rightarrow E \rightarrow C \rightarrow D
\]
Hence, the correct answer is:
\[
\boxed{\text{(C) B, A, E, C, D}}
\]
