Answer:
A
Step-by-step explanation:
Initially they were bombing the beach-heads during operation overlord (I.e the Normandy landings) but they missed severely due to bad weather. They also used the pilots to drop paratroopers. The supplies, water, and direction support, i'm not so sure because the hand-held (Not the backpack worn) radio wasn't invented until later, correct me if I'm wrong but this is all that I know.
