The accrued regime will treat this payment as:
C) one month as expense and the other two months as Active
Step-by-step explanation:
The entity pays three months advance on the first day of the period itself so the whole money is counted towards active and not as counted towards expense in this time.
The three months payment that is due is not thus paid on the first as is required.
It is only paid on the 30th of the first month by then the first month's rent had to have passed by.
So the one month's rent paid would be the expense that is paid up and not the advance while other two will be treated as advance only.
