I believe it would be the first option. It forms iron oxide (rust) when exposed to moisture and air.
To rank the effective nuclear charge Z* experienced by a valence electrons of a set of atoms that belong to a same period, you only need to apply the rule of trend: it increases as you move from left to right in the period.
So, lets do it for these atoms: P, Al, Si, Cl
The belong to a same period and the order is Al, Si, P, Cl (just see a periodic table). So the rank is Al < Si < P < Cl
Now, lets do it for these atoms:, Be, Ne, O, C
They belong to the second period. The order is Be, C, O, Ne
So, the rank is Be < C < O < Ne.

Answer:
c
Explanation:
I hope this may help you guys
I’m pretty sure it’s B since ones charge the neutral while ones is positive, it’s an obvious difference as well/
