Lets assume we are writing a system to backup a list of transactions: class Transaction 1 String TransactioniD: Date TranactionTime: Account account: enum Type(ADD, EDIT, ADMIN): Type type: Transactions are constantly added to the system as quickly as possible (hundreds a minute) and occasionally, your system will need to retrieve them but only if there is a error with the main system (once or twice per million transactions). Additionally, transactions may not come in order as some transactions take longer to process. What is the best way to store the transactions in your system? a) as a list sorted by transactionID b) As an unsorted list of transactions c) as a list sorted by transaction Time d) As a list sorted by a new systemiD int since they transactions are not coming into our system in order of time. Activate Windows Go to Settings to activate Windo e) As a 2d list with the columns sorted by Account and the rows sorted by date
