Explanation:
Introduction / Context:
This checks the logical manufacturing flow in metallurgy from ore to alloyed products.
Given Data / Assumptions:
Concept / Approach:
We respect the dependency chain: extract → process → purify → obtain metal → alloy.
Step-by-Step Solution:
Verification / Alternative check:
Skipping purification before metal would be incorrect; producing alloy before base metal is impossible.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing “process” and “purify”; purification is the cleaning step after initial processing.
Final Answer:
c, b, d, a, e
