C Correct answer
Explanation

Galileo discovered the isochronism of the pendulum in 1583 - that a pendulum's period depends only on its length, not the amplitude of swing. The telescope was his invention, not a discovery. Distoscope is not a real scientific instrument, and alarm clocks are unrelated to Galileo's work.
