I bet the correct answer is 'firstName' because the question is just testing if we can read. Seriously, who needs DataWeave when you have common sense?

B) customer.firstName is the way to go. Unless you're trying to invoke the spirit of Shakespeare with those 'vars' shenanigans.

I'm not sure, but I think C) vars.`customer.firstName` might also work because it combines vars and customer.firstName.

A) firstName? Really? Who names a variable just 'firstName'? That's like naming your dog 'Dog'. C'mon, people, get creative!

I disagree, I believe the correct answer is D) vars.`customer`.`firstName` because it uses the vars to access the customer's firstName.

D) vars.customer.firstName looks more elegant, but B) is the safer bet. Gotta play it safe in these exams, you know.
