Final answer:
The correct word to complete the sentence is 'c'est.'
Step-by-step explanation:
The correct word to complete the sentence is c'est.
Using the phrase 'Bonjour, moi je m'appelle Pierre et elle,' we need to fill in the blank to indicate the name of the person being referred to. In this case, we are introducing Sophie, so we use the singular form 'c'est' which means 'it is.' Therefore, the correct sentence is 'Bonjour, moi je m'appelle Pierre et elle, c'est Sophie.'
