Concept:
Art movements and techniques are identified by their visual features.
Sfumato belongs to Renaissance painting, Impressionism studies light, Pointillism uses colour dots, and Cubism uses geometrical forms.
Step 1: Match Sfumato.
Sfumato is a soft blending technique used in Renaissance painting.
So:
\[
A \rightarrow III
\]
Step 2: Match Study of light.
Impressionism focused on light, atmosphere and changing visual impressions.
So:
\[
B \rightarrow IV
\]
Step 3: Match Colour Dots in Painting.
Colour dots are associated with Pointillism.
So:
\[
C \rightarrow II
\]
Step 4: Match Geometrical forms.
Cubism uses geometrical and fragmented forms.
So:
\[
D \rightarrow I
\]
Step 5: Final matching.
The correct matching is:
\[
A-III,\ B-IV,\ C-II,\ D-I
\]
Hence:
\[
\boxed{\text{(C)}}
\]
