The Correct Option is C
Solution and Explanation
Concept:
Extrusion is a forming process in which a plastic ceramic mass is forced through a die to produce long products of uniform cross-section.
Step 1: Ceramic rods and tubes have continuous and uniform cross-sections.
Step 2: For such shapes, the ceramic body should be pushed through a shaped die.
Step 3: In extrusion, a plastic clay body is forced through a die opening. \[ \text{Plastic ceramic mass} \rightarrow \text{Die} \rightarrow \text{Rod/Tube} \]
Step 4: If the die opening is circular, rods can be formed.
Step 5: If the die has a hollow shape, tubes can be formed.
Step 6: Slip casting is used for hollow complex shapes, pressing is used for compact shapes, and injection molding is used for complex small ceramic parts. Therefore, the technique used for ceramic rods and tubes is: \[ \boxed{\text{Extrusion}} \]
