Final answer:
The hot fudge Kahlua brownie usually has walnuts but you can ask for a nut-free version if the establishment can accommodate such requests.
Step-by-step explanation:
The hot fudge Kahlua brownie typically contains walnuts, making 'C) Walnuts' the correct answer. However, many establishments that offer desserts like this brownie are willing to accommodate customers with different dietary preferences or allergies. You should ask if they can provide a nut-free option or omit the nuts from the dessert. If it is possible to order the dessert without nuts, then 'D) No nuts (nut-free option available)' would also be accurate. Be sure to communicate your dietary needs clearly when ordering.
