An individual working outside or inside an organization who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others.

• A. Inventor
• B. Lone inventor
• C. Designer
• D. Engineer

Answer: (B)

Solitary pursuit of a novel product, especially when the ideas imply change and meet resistance, describes someone who works outside or inside an organization but remains isolated because of the strength of their vision. This is the essence of a lone inventor—someone who pursues new ideas often on their own, and whose commitment to change can lead others to push back or disengage, leaving the inventor working apart from the mainstream team. This fits best because the term explicitly signals independence and isolation due to radical ideas. The other roles focus more on applying existing knowledge or collaborating on design or technical work and don’t inherently imply the same level of social resistance or solitary pursuit.
