I'm tempted to take (C), but I'll go with (E).
proof is for the health threat, so (E) seems a good choice.

between (C) and (E, I pick (C)

(C) (after restructuring) :
Although no proof that electromagnetic fields generated by household appliances pose any threat to health yet exists, mounting scientifc evidence has convinced many experts that there is cause for concern.

Restrictive Clause modifying Proof: that electromagnetic fields generated by household appliances pose any threat to health

(E) : Grammatically seems correct but it is having passive construction.

(A), (B) says "proof of electromagnetic fields", which is wrong.

(D): says Proof poses any threat..., which is wrong..

I am not sure why A is incorrect. If you read the highloghted portion it is idiomatic.

Although no proof yet exists of electromagnetic fields generated by household appliances posing any health threat, mounting scientifc evidence has convinced many experts that there is cause for concern.

Its like saying no proof of a theorem exists.

all other constructions seem incorrect. Other close call is C.

I ll go for E.

The proof of health treat from something has not been yet proven

BUT

Scientific raises concern that they might be some health threat (not electromagnetic ....).

so Health threat is the center / topic / main point of the sentence

C)

A) and B) are out because it sounds like that there exists no proof for the electromagnetic fields...

D) is out because of wrong word order

E) same as D)
