Final answer:
The Allied successes in Operation Torch, D-Day, and Stalingrad forced Germany into a defensive stance but did not lead to immediate annihilation, surrender, or peace negotiations with Germany.
Step-by-step explanation:
After the success of the D-Day invasion, Operation Torch, and the Battle of Stalingrad, the Allied powers achieved a significant turn in World War II, essentially forcing Germany into a defensive position which ultimately led to its defeat. While each of these operations had a profound impact, it is inaccurate to claim they resulted in any of the extremes listed in options a) or c).
Although Operation Torch and D-Day put pressure on Germany from the West, and the Battle of Stalingrad was a turning point on the Eastern Front, Germany did not surrender until May 1945. Thus, the most accurate conclusion is that none of the presented options are entirely correct as these victories did not immediately result in the annihilation of the German military, expansion of German territory, or Germany's unconditional surrender during these operations, and it was not a case of the Allies offering peace negotiations.
