Final answer:
The correct word or expression to complete the sentences is 'OA al restaurante'.
Step-by-step explanation:
The correct word or expression to complete the sentences is OA al restaurante. This means that after going to the cinema, the parents go to the restaurant to eat. The word 'al' is a contraction of 'a' (to) and 'el' (the), and it is used to indicate that they are going to a specific place. The other options, OB. al parque (to the park), C. al templo (to the temple), and OD. al campo (to the countryside) do not fit the context of going to eat after going to the cinema.
