A flame effect defined as the combustion of solids, liquids, or gases to produce phenomena before an audience.

• A. Direct ignition
• B. Fire
• C. Flame Effect
• D. Automatic Flame Effect

Answer: (C)

The concept tested is a controlled, audience-facing display created by burning fuels. This description matches a flame effect because it defines the visual phenomenon produced by combustion specifically for view by an audience, meaning it’s an intentional stage effect rather than just any fire or the act of lighting something.

Direct ignition is just the act of lighting something on fire, not a sustained, designed display for spectators. Fire refers to the general phenomenon of burning, not a defined performance effect. Automatic flame effect implies a specific system or automation, but the definition here centers on the effect itself, not how it’s triggered.
