Concept:
- An idiom carries a figurative meaning different from the literal words used.
- 'Foot the bill' means to pay for the cost of something.
Step 1: Recall the meaning of the idiom
'Foot the bill' figuratively means to take on the payment or expense of something, it has nothing to do with feet.
Step 2: Read the sentence for context
Seema hosted the feast while her father chose to 'foot the bill', meaning he took charge of some part of the arrangement, which the idiom tells us is the expense.
Step 3: Eliminate the wrong options
'Arrange the decoration', 'arrange the guest list' and 'arrange to entertain the guests' are all activities unrelated to paying money, so they do not match the idiom.
Step 4: Match with the correct meaning
'Arrange to bear the expenses' is exactly what 'foot the bill' means.
Final Answer: arrange to bear the expenses
