Answer 2

If you go to ptable.com then the properties tab and select conductivity you can compare them like I did. The answer is D.

Normally I would explain this but Conductivity is difficult to define as a trend on the periodic table. Especially when the elements are far apart.

Answer 3

I would say it's C.
Mn is a metal, so it is the most conductive.
Ge is a semiconductor, so it is less conductive than metal, but more than an insulator
O is an insulator.

So in order of decreasing conductivity, it is Mn, Ge, O.

Answer 4

The answer was C. Thank you both for helping :)
