What renewable energy source has ABC installed at all factory sites?

• A. Wind turbines.
• B. Solar panels.
• C. Geothermal systems.
• D. Hydro power.

Answer: (B)

This item tests how a company chooses a renewable energy solution that can be deployed across multiple factory sites. Solar panels are particularly well-suited for this because they can be installed on rooftops or in available spaces at each site with minimal land use, and they’re easily scalable—capacity can be added as needed without major infrastructure changes. They also generate electricity close to where it’s used, helping reduce transmission losses and simplify budgeting across many locations.

Other options have more deployment challenges: wind turbines require suitable open space with consistent wind and can raise noise and zoning concerns; geothermal systems depend on specific underground conditions and large upfront costs; hydro power needs a reliable water source and significant infrastructure. These constraints make large‑scale, uniform installation across all factory sites less practical, so solar panels across all sites best meet the goal.
