Final answer:
Wave-particle duality does not exist for objects on the macroscopic scale.
Step-by-step explanation:
A. False
Wave-particle duality is a fundamental concept in quantum mechanics that suggests that particles and waves can exhibit both wave-like and particle-like properties. This phenomenon has been observed and well-documented for subatomic particles like electrons and photons. However, on the macroscopic scale, objects like everyday objects and even larger particles like baseballs do not demonstrate wave-particle duality.
