Answer:
C. carryout service
Explanation:
A restaurant that is allowing their customers to take food away, if offering a carryout service, also known as take-out service. That's for example when you go to McDonald's and then bring your order back at home to eat it.
A buffet service is when the restaurant offers a wide variety of dishes already prepared and you go to the buffet tables to fill your plate with a bit of this, a bit of that... oh and a double portion of that one!
A cafeteria service is like you have at school. You form a line to get your food from series of stations (soup, main dish, dessert, drinks), putting your items in a tray then pay... and then hope to find an empty table to eat your lunch.
A counter service is when you go eat in a dinner for example, and you sit on a bench and eat on a long table, called a counter. That's usually for a quick meal.
