Bill is swiping his credit card in the supermarket. His wife is paying a bill online at home.
Bill sees this on the screen:
Your old balance is: $2000
Your debit is: $100
Your new balance is: $1850

His wife sees this on the screen:
Your old balance is: $2000
Your debit is: $50
Your new balance is: $1950

Which one of the following could have occurred?

(a) race condition
(b) condition synchronisation
(c) starvation
(d) mutual exclusion

I think this is a race condition. Am I right?
