a phenomenon ......... is a noun modifier and modifies the nearest noun which happens to be Peru for options A,B, & C
whereas the s/c is not intended to do so. therefore A,B & C are out

E is wrng bcoz where is used to modify a place phenonmenon is not a place.......

hence D is correct......

IMO (D).


EI Nino ..... is a phenomenon is correct sentence. E is wrong because... where is used to modify a place only.
