In electron transport process the excited electron from PS II to Pheophytin is accepted by primary acceptor quinone, which sends them to an electron transport system consisting of plastoquinone(PQ), cytochrome complex and plastocyanin(PC).

The excited electron absorbed by PS I reaction centre, then transfer to the ferredoxin (Fe), then the reduced Ferredoxin donates the electron to NADP⁺.

Hence, the correct answer is 'iii,ii,i,iv'.
