The Correct Option is B

Solution and Explanation

Step 1: Concept
Simple Harmonic Motion (SHM) is a special type of periodic motion.

Step 2: Meaning

Periodic motion is motion that repeats itself after equal intervals of time.

Step 3: Analysis

In SHM, acceleration is directly proportional to displacement and directed opposite to it ($a \propto -x$).

Step 4: Conclusion

Among the given options, the defining characteristic is that the motion is periodic. Final Answer: (B)
