Correct option is D
· The statement indicates a target to reduce carbon emissions by 50% within the next decade. However, it does not specify the exact measures that will be taken, such as banning all fossil fuel vehicles or shutting down all coal-fired power plants.
· Conclusion I suggests an immediate ban on all fossil fuel vehicles, which is not directly mentioned or implied in the statement. The policy could involve a range of measures, not necessarily an immediate ban.
· Conclusion II suggests shutting down all coal-fired power plants, which is also not directly mentioned or implied in the statement. The reduction in carbon emissions could be achieved through various means, not necessarily by shutting down all coal-fired plants.
Since neither conclusion is directly supported by the statement, we cannot assume them to be true based on the given information.
Answer: (d) Neither Conclusion I nor Conclusion II follows.
