The best answer is: The invasion exhausted German supplies and weakened their defenses.

Explanation: D-Day opened a major Western front, forcing Germany to divert troops and matériel from the Eastern Front and other theaters, stretching its resources and weakening its overall defenses. That made the Europe‑First plan (defeat Germany before focusing on Japan) achievable. (It did not immediately force Germany to surrender, nor did it have any realistic effect on German ambitions to invade the U.S.)
