Citizen science

Citizen science

• A. Online learning
• B. Crowdfunding
• C. E-commerce
• D. Citizen science

Answer: (D)

Citizen science is about everyday people actively participating in real scientific research. It goes beyond just learning or funding; volunteers can collect data, make observations, or help analyze results for researchers. That collaboration between scientists and the public is what defines citizen science. For example, people might track bird migrations, record phenology data, or help classify galaxies in online projects. This shows why the option naming citizen science is the best fit: it explicitly describes non-professional participation in scientific work. The other activities describe online learning, which is about studying content; crowdfunding, which is about raising money; and e-commerce, which is buying and selling goods online. None of those inherently involve contributing to scientific research the way citizen science does.
