what practice by retreating soviet troops prevented resource gains for german troops?\nthe soviets froze the oil inside the military tanks.\nthe soviets initiated a blitzkrieg against the germans.\nthe soviets enacted a scorched earth policy.\nthe soviets cut off the supply lines from the axis powers.
Answer
Brief Explanations:
The scorched - earth policy involves destroying anything that could be useful to the enemy, such as resources, infrastructure. When retreating, Soviet troops used this policy to prevent German troops from gaining resources. Freezing oil in tanks is not a common large - scale resource - denying practice. The Soviets did not initiate blitzkrieg against Germans as it was a German military tactic. Cutting off Axis supply lines is not a practice by retreating Soviet troops to deny resources to Germans.
Answer:
The Soviets enacted a scorched earth policy.
