Step 1: Matching dimensions.
- Thermal Conductivity has dimensions \( [MLT^{-3}K^{-1}] \), which matches with (R).
- Boltzmann constant has dimensions \( [M L^1 T^{-2}] \), which matches with (P).
- Spring constant has dimensions \( [M L^1 T^{-3} K^{-1}] \), which matches with (S).
- Surface tension has dimensions \( [M L^1 T^{-2}] \), which matches with (S).
Step 2: Conclusion.
From this, the correct matching is (1).
Final Answer:
\[
\boxed{\text{A } \rightarrow \text{R; B } \rightarrow \text{P; C } \rightarrow \text{S; D } \rightarrow \text{S}}
\]
