Final answer:
The correct verb form to complete the sentence is 'choisirais'.
Step-by-step explanation:
The correct verb form that completes the sentence is choisirais.
Since the sentence starts with the subject 'Je' (meaning 'I' in English), we need to use the verb form that matches with the first person singular. The verb 'choisir' (meaning 'to choose') conjugates as follows:
Je choisirais - I would choose
Tu choisiras - You will choose
Il/Elle choisirait - He/She would choose
Therefore, the correct answer is choisirais because it matches with the subject 'Je'.
