A student made the following observations:

(i) Clean copper metal did not react with 1 M Pb(NO₃)₂ solution

(ii) Clean lead metal dissolved in 1 M AgNO₃ solution and crystals of Ag appeared

(iii) Clean silver metal did not react with 1 M Cu(NO₃)₂ solution

The order of decreasing reducing character of the three metals is-

A
