What limitations did the Treaty of Versailles impose on German aviation?

The correct answer highlights that the Treaty of Versailles imposed significant restrictions on Germany's military aviation capabilities as a consequence of World War I. Under the treaty, Germany was required to limit the size of its military, which included strict limitations on the number and types of military aircraft it was allowed to possess. This aimed to prevent Germany from reconstituting a powerful air force that could threaten European stability in the years following the war.

The imposition of these limitations was a part of the broader efforts to diminish Germany's military strength and prevent future conflicts. As a result, Germany had to dismantle much of its military aviation infrastructure and significantly reduce any potential for aircraft manufacturing dedicated to military purposes.

In contrast, the other choices do not reflect the constraints imposed by the treaty. While Germany was not entirely barred from aircraft manufacturing, it could not engage in military aviation as it previously had. The notion that the treaty promoted growth in German aviation technology is misleading; in fact, the restrictions hindered development in this area. Overall, the treaty was a reaction to the war's devastation, and its aim was to ensure that Germany would not be able to wage war in the future through a robust military aviation program.
