Which Method of the following inventory valuation method results in the same Amount under periodic and perpetual inventory Systems?

Under periodic and perpetual inventory system the FIFO method is best for inventory valuation

with inflation assumption it will be FIFO

I think LIFO and FIFO is the best method to valuation.

A- FIFO valuation do not depend on the choice of a periodic or perpetual system. As sales occur, the cost is always presumed to be from the oldest goods in stock. This occurs whether the computation is made only once at the end of the period or throughout the period. The other method would yield different result under a periodic versus a perpetual system, as the units presumed to be sold are sensitive to the timing of the sales.

FIFO method is give the same amount.

FIFO and LIFO are cost layering methods used to value the cost of goods sold and ending inventory
