3. For the question regarding renewable and non-renewable natural resources, the correct answer for a non-renewable resource is: b) Los combustibles fósiles. Fossil fuels, such as coal, oil, and natural gas, are examples of non-renewable resources because they take millions of years to form and cannot be replenished on a human timescale. Once these resources are depleted, they are gone, making them finite and non-renewable compared to resources like forests or rivers which can replenish themselves over time.
