While Platinum in a car's catalytic converter does help in removing toxins from automobile exhaust, it cannot be concluded that advances in catalytic converters can solve emission problems. This would depend on the precise advancement that takes place and the role of platinum in the same. Hence, option (A) can be ruled out.
Options (B) and (D) are incorrect since the catalytic converter in a car's battery is not an industrial application. Since the new Raney-Ni-Sn catalyst is capable of performing for relatively longer periods and at lower temperatures, it is a significant advance in producing hydrogen fuel from alternative sources. Hence, (B) is the best choice.
