The sustainability of biodiesel compared to ethanol is not directly related to the value of corn and soybeans as cash crops, nor the fact that no one in Russia grows soybeans. The sustainability of a biofuel is determined by various factors including its production process, its impact on the environment, and its overall energy balance.

In terms of soil health, soybeans can be considered more sustainable than corn. Soybeans, like other legumes, have the ability to fix nitrogen from the atmosphere into the soil, which can improve soil fertility. This is not the case with corn. Therefore, the statement "Soybeans are better for the soil than corn" (C) is correct and contributes to the sustainability of biodiesel (which can be made from soybeans) compared to ethanol (which is often made from corn).

However, it's important to note that the sustainability of biofuels is a complex issue and can't be determined by a single factor. Other factors such as the energy input required for production, the impact on food supply and prices, and the greenhouse gas emissions over the lifecycle of the fuel also need to be considered.
