Which of the following describes an invention?

An invention is fundamentally characterized by the creation of a new product or process that emerges from rigorous study and experimentation. This definition captures the essence of innovation, which inherently requires a novel approach or idea that has not previously existed. Unlike enhancements or variations that may improve upon existing technologies or designs, a true invention introduces something distinct and original. The process of developing an invention typically involves experimentation, testing, and overcoming various challenges, which differentiates it from adaptations of existing technologies or mere modifications. Understanding this distinction is crucial in fields like engineering and technology, where the innovation process is central to advancement and growth.
