during the final years of world war ii, how did the allies gain control of the north atlantic?\nthey used u - boats to sink german ships.\nthey used fighters to provide air support for their ships.\nthey used better anti - submarine technology.\nthey used allied submarines to defeat german ones.
Answer
Answer:
C. They used better anti - submarine technology.
Brief Explanations:
During WWII, the Allies improved anti - sub tech to counter German U - boats and gain North Atlantic control. U - boats were German, not Allied (A is wrong). Air support alone wasn't decisive (B is insufficient). Allied submarines weren't key to gaining control over German ones (D is incorrect).
