Statistics show that the domestic automobile sales in September totaled around 1.6 million units, ending the record of 7 consecutive months of positive year-on-year growth. The production and sales of Japanese cars have fallen sharply, falling by about 40% at the same time. In contrast, independent brands account for about 42.7% of total passenger vehicle sales, which is the second highest sales record this year. Therefore, relevant experts judge that the sales of independent brand vehicles will enter a period of rapid growth. Which of the following, if true, best supports the above conclusion? ['In September, a Japanese brand car was exposed to quality problems, affecting the overall sales of Japanese cars.', 'In the fourth quarter, the sales of self-owned brand cars are still higher than those of other brands, and continue to grow.', 'In September, in addition to Japanese cars, German and American cars were not as good as their own brand cars.', 'Car sales statistics do not include unlicensed cars, and there are a large number of unlicensed cars.']
