1. Click "submit" to complete the application process.
2. When you're finished, click "submit" to send in your application.
3. Click "submit" when you are all done with your application.

Answer 1

1. Click "submit" to complete the application process.

Reason: It uses formal phrasing ("complete the application process") and no contractions or colloquial language ("you're," "send in," "all done"), making it the most formal of the three.
