New knowledge which leads to development of new or improved products, processes or ideas.

• A. Inventions
• B. Discoveries
• C. Innovations
• D. Technologies

Answer: (C)

Applying knowledge to create new or improved products, processes, or ideas is about turning ideas into real value. This is what innovations are: taking what we know and applying it in ways that produce better or new solutions that people can use. An invention, by contrast, is a newly created device or method itself, but it isn’t necessarily adopted or improved for real-world value. A discovery is finding something new about the world, which is knowledge, but doesn’t imply applying it to make improvements. Technologies are the tools and systems that come from applying knowledge, but the focus of this statement is on the act of applying knowledge to develop improvements, which is the essence of innovations. So the best fit is innovations.
