Question

using co-generation to create electricity can help improve efficiency in power plants to as high as which of these? 90% 10% 25%

Explanation:

Co-generation (combined heat and power) captures waste heat from electricity generation for other uses, drastically boosting overall plant efficiency far above traditional power plants which typically have 30-50% efficiency. The high efficiency achievable with co-generation reaches up to 90%.
