German scientists were concerned about Nazi restrictions on uranium sales because •uranium would not be available for industrial research.
•uranium was important to German missile programs.
•uranium paid for German scientific research.
•uranium could be used in research on atomic weapons.

uranium would not be available for industrial research.

Explanation:

The Nazi's aware that the radiation from the Uranium caused massive health risk. They started a nuclear weapons program in 1930s, but the experiments that they did ended up in failures. They're pretty late in finding out the solutions to minimize the side effect.

The Nazi's restricted the sales of Uranium so they have more materials to conduct more experiments. But, the scientists saw other purposes for it. They can be used for industrial research to potentially found a new energy source that is far cheaper and cleaner compared to the oil.
