Concept:
Modern Indian sculptors use a wide range of materials such as copper, marble, terracotta, and fibreglass to create expressive sculptural forms.
Step 1:
S. Nandagopal was famous for metal sculptures created using welded copper techniques.
Thus:
\[
A \rightarrow II
\]
Step 2:
Ravinder Reddy is known for monumental sculptural heads and figures often executed in marble and painted fibreglass.
In this case:
\[
B \rightarrow I
\]
Step 3:
Pradosh Dasgupta experimented with terracotta and modern sculptural forms.
Thus:
\[
C \rightarrow III
\]
Step 4:
N. Pushpamala worked with fibreglass and painted sculptural surfaces.
Thus:
\[
D \rightarrow IV
\]
Therefore, the correct matching is:
\[
A-II,\; B-I,\; C-III,\; D-IV
\]
Hence, the correct answer is:
\[
\boxed{\text{(1) A-II, B-I, C-III, D-IV}}
\]
