Analogy — “Ohm : Watt : Ampere”. Choose the option that is also an electrical unit (to match the category).

Introduction / Context:
Ohm (resistance), watt (power), and ampere (current) are electrical units. We must select a choice that is also a unit from electricity.

Given Data / Assumptions:

• Stick to SI/derived electrical units.

Concept / Approach:
“Volt” is the SI unit of electric potential (voltage). “Hour” is a time unit; “Electricity” and “Light” are general nouns; “Lumen” is a photometric unit (luminous flux), not an electrical unit.

Step-by-Step Solution:

Verification / Alternative check:
Physics conventions confirm volt alongside ohm, watt, and ampere as standard units.

Why Other Options Are Wrong:
They are not electrical units.

Common Pitfalls:
Mixing photometric and electrical units.

Final Answer:
Volt
