Assuming that the prepayment has not been recorded, then $5,688 is the amount that was paid for the year to 28 February 2021.
Therefore, as at 31 December 2020 they have prepaid 2/12 x 5688 = 948, and the expense in the SOPL is 10/12 x 5688 = 4,740.
This is all explained in my free lectures on accruals and prepayments. The lectures are a complete free course for Paper FA and cover everything needed to be able to pass the exam well.
