Concept:
In Indian iconography, standing postures are important for identifying sculptural forms.
Samabhanga, Abhanga, Tribhanga, and Atibhanga represent different degrees of body bending.
Step 1: Match Samabhanga.
Samabhanga means equal balance or straight standing posture.
So,
\[
A \rightarrow II
\]
Step 2: Match Abhanga.
Abhanga means slight bend, generally one knee is bent while the body remains mostly straight.
So,
\[
B \rightarrow I
\]
Step 3: Match Tribhanga.
Tribhanga means three bends in the body.
So,
\[
C \rightarrow III
\]
Step 4: Match Atibhanga.
Atibhanga shows more dramatic movement involving three or more limbs.
So,
\[
D \rightarrow IV
\]
Thus, the correct matching is:
\[
A-II,\ B-I,\ C-III,\ D-IV
\]
Hence:
\[
\boxed{\text{(A)}}
\]
