The Correct Option is A
Solution and Explanation
To match casting methods with their most typical products, we recall the characteristics of each process.
Step 1: Continuous casting (P).
This method is used for producing long, uniform cross-section products such as slabs, billets, and strips.
Thus, P corresponds to:
\[
3\; \text{Slabs and strips}
\]
Step 2: Investment casting (Q).
This method is used for thin, intricate, and complex-shaped components due to excellent dimensional accuracy and surface finish.
Thus, Q corresponds to:
\[
1\; \text{Thin and intricate components}
\]
Step 3: Centrifugal casting (R).
This is used for manufacturing hollow axisymmetric parts such as pipes and cylinders using radial centrifugal force.
Thus, R corresponds to:
\[
2\; \text{Hollow axisymmetric parts}
\]
Step 4: Final mapping.
\[
P-3, Q-1, R-2
\]
This matches option (A).
Final Answer: (A)
