The statement is in the form of "No A are non-B", which can be converted to "No non-B are A". Both statements convey the same information, so conversion is valid in this case. Contraposition is also valid here, but it is not necessary to use it as conversion suffices. Obversion is true, but it does not preserve the original structure of the statement, so it is not the best choice.
