    Question on Concurrency concept

    1004380
      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?
