Answer: The most likely instruction that Adele would use when telling her friend how to make an apple pie is:
B. Tranchez les pommes en lamelles, s’il vous plaît.
Option B is the most appropriate because it uses the polite form "s’il vous plaît" (please), which indicates Adele's courteous manner when instructing her friend. The verb "tranchez" (slice) is conjugated in the imperative form to give the instruction "Slice the apples into thin slices."
