Final answer:
A food worker may drink from a water cup with a lid and straw while working, as it helps minimize contamination risks in the workplace.
Step-by-step explanation:
A food worker can drink while working, but there are specific guidelines that must be followed to ensure food safety and workplace health regulations are respected. The correct answer to what a food worker may drink while working is d. A water cup with a lid and straw. This is because a sealed container minimizes the risk of spills and contaminations, which can occur with open containers such as a can of soda, a mug of coffee, or an open cup of lemonade. Having a lid and a straw further reduces the chances of hand-to-mouth contamination and prevents foreign objects from entering the drink.
