Final answer:
The correct word to complete the sentence is 'es'.
Step-by-step explanation:
The correct word to complete the sentence is es. The phrase 'Pamela es peruana' means 'Pamela is Peruvian' in English. In Spanish, the verb 'ser' (meaning 'to be') is used to express nationality, and we use 'es' (the third-person singular form of 'ser') to agree with the subject 'Pamela.'
