In order to track the number of deposits, the transactionCount variable must be incremented every time a deposit is made. Option B is the only one that correctly increments transactionCount. Option A updates the balance but does not track the transaction count. Option C incorrectly sets transactionCount equal to the deposit amount. Option D replaces the balance with the sum of the transactionCount and the deposit amount, which is not the correct way to update the balance.
