(C) The correct matching is as follows:$A$. Tapetum: It is the innermost layer of the microsporangium wall that provides nourishment to the developing pollen grains $(A-iv)$.$B$. Intine: It is the inner wall of the pollen grain,which grows out to form the pollen tube during germination $(B-iii)$.$C$. Vegetative cell: It is a large cell in the pollen grain that contains abundant food reserves and eventually degenerates during the development of the male gametophyte $(C-i)$.$D$. Sporopollenin: It is one of the most resistant organic materials known,which forms the exine of the pollen grain $(D-ii)$.Therefore,the correct sequence is $(A-iv), (B-iii), (C-i), (D-ii)$.
