if arial is planning on leaving the money in the account for 4 years and then withdrawing all funds, then the is the better choice earning her more.

Account B is the better choice for earning her (6751.25 - 6710) = $41.25 more.  

Step-by-step explanation:

Now, Account B will pay 4.5% simple interest and if the account is left open for longer than 3 years, then at the end of the third year a bonus account will be opened with $250 that also earns 4.5% for the remainder of the time the initial account is open.
