According to the instructions or guidelines provided in the text, particularly "・持ち物：エプロン、三角巾、手拭きタオル", the required action or next step is clearly defined. Therefore, the option "エプロンと三角巾と手拭きタオル。" is the only correct choice as it matches the specified rules. A successful strategy for action-based questions is to carefully match dates, times, or conditional rules in the text to avoid distractors. The incorrect options violate these specific conditions or outline steps that are not recommended in the passage.
