AThe speed of sound in water

BThe temperature of the air

CThe distance to an object without touching it

DThe brightness of a light source

Step-by-Step Solution

Solution:

Step 1: Understand the sensor's purpose
The DistanceSensor uses sound waves to detect how far an object is without physical contact.
Step 2: Identify the correct measurement type
It measures distance, not temperature, speed, or brightness.
Final Answer:
The distance to an object without touching it -> Option C
Quick Check:
DistanceSensor measures distance = C [OK]

Quick Trick: Remember: ultrasonic means measuring distance by sound [OK]
