Answer:
Based on the provided options, Lily would need to follow the following standards when setting wing and aisle stacks:
- Limit features in the middle of the aisle to one per aisle.
- Price each feature with approved EDLP (Everyday Low Price) signing.
Step-by-step explanation:
The option "Build aisle and side stacks on Friday morning and remove by Sunday afternoon" pertains to the timing and duration of setting up the stacks, rather than a specific standard to follow. The option "Price selected features with EDLP signing" is not specific about pricing each feature, whereas the option "Price each feature with approved EDLP signing" provides the specific standard of pricing each feature with approved EDLP signing.
