Correct:
C
Explanation
An odometer (or odograph) is an instrument used for measuring the distance travelled by a vehicle, such as a car or a bicycle. It can be mechanical, electronic, or a hybrid of both.
- Speedometer: This device measures and displays the instantaneous speed of a vehicle while it is in motion.
- Cathetometer: This is a precision laboratory instrument used to measure vertical distances, such as the height of a liquid column in a glass tube.
- Lactometer: This is a specialized hydrometer used to test the purity of milk by measuring its density or specific gravity.
Since the question specifically asks for the device that records the distance covered, the odometer is the correct answer.
