Recently, a research team successfully developed a semiconductor material with excellent energy-saving effects by using blue light-emitting diodes (LEDs) and produced a small semiconductor of about 1 mm square, which can stably transmit the 10 amps required during the use of home appliances. Electricity. If it is used in appliances such as air conditioners, it can save nearly 10% of power consumption. The research team believes that home appliances produced using this new type of semiconductor material will be more competitive in the market than traditional home appliances. Which of the following, if true, best supports the above conclusion? ['This new semiconductor material can also be used in the production of electric vehicles in the future.', 'The quality of household appliances claimed to be energy-saving is currently uneven in the market.', 'Several well-known home appliances companies in the world have launched commercial research cooperation with the research group.', 'The cost of household appliances produced with this new material is expected to reach a level similar to traditional household appliances in the future.']
