Correct option is C
Explanation: A periodic signal is a signal that repeats its pattern at regular intervals, meaning it has a definite pattern that keeps coming back after a specific time period.
Dependent signal: This term might refer to a signal that depends on another signal's values, but it doesn't necessarily imply a repeating pattern.
Independent signal: An independent signal is one that doesn't depend on any other signal, but it also doesn't necessarily have a repeating pattern.
