Answer: A
Step-by-step explanation:
A.) The most logical choice. He should bring his personal information if there is a chance he needs to immediately fill out the application.
B.) The company REQUIRES the paper application before he can even apply for the job. It would not be smart for him to prepare for an interview he won't be able to go into because he didn't fill out the application.
C.) While this isn't a the worst option, there may be a chance he will have to fill out the application on the spot (as mentioned in choice A). Chances are, he'd have to drive back and gather his personal information if he forgets it. Not the best usage of time.
D.) Ivan still has an interview to do after completing his job application. It isn't guaranteed that he will start working just because he filled it out.
