5070Reactivity series

The reactivity series for some metals, with two gaps labelled X and Y, is shown. most reactive → least reactive K Na Ca Mg X Zn Y Pb (H) Cu Ag Which row correctly identifies metals X and Y and the method of extraction of Y from its ore?

  1. Ametal X: Al, metal Y: Fe, method of extraction of Y: electrolysis
  2. Bmetal X: Al, metal Y: Fe, method of extraction of Y: reduction with carbon
  3. Cmetal X: Fe, metal Y: Al, method of extraction of Y: electrolysis
  4. Dmetal X: Fe, metal Y: Al, method of extraction of Y: reduction with carbon
