1.	Red hot carbon will remove oxygen from the oxides `XO` and `Yo` but not from `ZO.Y` will remove oxygen from `XO`. Use this evidence to deduce the order of activity of the three metals `X,Y,` and `Z,` putting the most reactive first.A. X , Y , ZB. Z , Y , XC. Y , X , ZD. Z , X, Y
Answer» Correct Answer - B Carbon does not reduce ZO and thus Z is more reactive . Also Y removes oxygen from XO and thus Y is more active than X . Thus activity order is Z , Y , X .
