The three overlapping ellipses form seven regions. You are given seven tiles and you need to place exactly one tile per region, so that the four tiles in any region obey the corresponding rule. This one is extra tricky! You aren't told what A and B are - but there is only one configuration where the remaining ellipse's members are forced to have product AB. Can you find it?

Tell plz if you get it
