The following metals are in order from most reactive to least reactive:

1. Zn, 2. Pb, 3. Cu, 4. Ag

Could someone please explain to me why their cations are in the OPPOSITE order in respect to reactivity?

4.	In a series of chemical test reactions the following observations were made when several metallic eleÂment samples were treated with 3.00 M hydrochloric acid solution. Zn: metal dissolves, hydroÂgen gas is emitted. Cu: no reaction. Ag: no reaction. Mg: metal dissolves, hydrogen gas is emitted. Mn: metal dissolves, hydrogen gas is emitted. Which statement below is true?
	A.	Mg, Mn, Zn are more reactive than Ag, Cu; but less reactive than H₂.
	B.	Mg, Mn, Zn are less reactive than Ag, Cu; but more reactive than H₂.
	C.	Mg, Mn, Zn are more reactive than Ag, Cu; and more reactive than H₂.
	D.	Mg, Mn, Zn are less reactive than Ag, Cu; and less reactive than H₂.
	E.	These observations are insufficient to form any judgment about relative reactivity of any of the elements tested.

my answer key states that the answer is B but im just confused why because according to the activity series of metals, Mg, Mn and Zn are more reactive than Cu and Ag

Can someone please solve some or all. Please Number the questions. Thank you so much!
