'possibility of' is the idiom here.Hence A,B,D are out.

Coming to C - instead of on - 'the' would be a better choice.

E is left.

IMO C...

because seriously impact parallels to severely impede.....

please advice...

'seriously impact on' is not correct usage.
It should be 'seriously impact industrialized nations'.
Therefore B and C are incorrect.

A has a problem because the sentences uses 'serious impact to'. It should be 'serious impact on'.

Between D and E, the 'possibility of' is the correct usage. Hence E is right.

I believe the best option is 1 below
1) could seriously impact industrialized nations and could severely diminish/impede or
Since we don't have that option 2) works.
2) could have a serious impact on nations and could severely diminish

The usage of have might be confusing but it is the best choice we are left with.

C is out because impede != diminish
