Electro-related terms in practical/technological sequence: Arrange Electrification, Electrician, Electrolysis, Electroplating, Electrotyping into a logical order of provision, personnel, and processes.

Introduction / Context:
The terms relate to supplying electricity, the professional who works with it, and industrial processes using electric current. We must place them in a sensible progression.

Given Data / Assumptions:

• Items: Electrification (supplying/installing power), Electrician (skilled worker), Electrolysis (chemical decomposition by current), Electroplating (metal coating), Electrotyping (replica/printing plate creation).

Concept / Approach:
A practical sequence is: first ensure electric power infrastructure (electrification), then the professional context (electrician). With power and expertise available, specific current-based processes can be executed: electrolysis, then electroplating, and finally electrotyping (an application that historically follows plating techniques).

Step-by-Step Solution:
Electrification → provides power.Electrician → installs/maintains/operates systems.Electrolysis → fundamental process using current.Electroplating → practical coating application based on electrolytic principles.Electrotyping → specialized replication leveraging plating methods.

Verification / Alternative check:
Historical manufacturing sequences in printing and metal finishing show electrotyping after plating foundations.

Why Other Options Are Wrong:
They misplace the provisioning step or put specialized applications before prerequisite fundamentals.

Common Pitfalls:
Assuming alphabetical order rather than functional dependency.

Final Answer:
Electrification, Electrician, Electrolysis, Electroplating, Electrotyping
