Correct option is C
(C) Carbon credits are traded at a price fixed from time to time by the U.N. Environment Programme
The statement is incorrect because carbon credits are traded on the open market and their price fluctuates based on supply and demand. The United Nations Environment Programme (UNEP) does not fix the price of carbon credits. The system allows for trading credits to encourage industries and countries to reduce their emissions by either implementing eco-friendly practices or purchasing credits from those who have already reduced their emissions.
