Final answer:
An 'electronic eye' controlled flushometer is classified as an 'Automatic flushometer.' It operates hands-free and uses sensor-based technology for flushing, thereby enhancing hygiene.
Step-by-step explanation:
A flushometer that is controlled by an “electronic eye” is classified as a c. Automatic flushometer. This type of flushometer operates on a sensor-based mechanism that triggers the flushing process hands-free, reducing the spread of germs and increasing hygiene.
Unlike manual flushometers, which require a user to press a button or lever to flush, or gravity flushometers, which rely on water tanks and gravity, an automatic flushometer uses advanced technology to detect when a flush is necessary and initiate it automatically.
