The rough endoplasmic reticulum (RER) is so named for the appearance of its outer surface, which is studded with protein-synthesizing structures known as ribosomes. Smooth endoplasmic reticulum (SER), a meshwork of fine tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids.The Golgi apparatus, functions as a factory in which proteins received from the ER are further processed. Protein processing within the Golgi involves the modification and synthesis of the carbohydrate portions of glycoproteins.Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump. Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides.Hence, a-iv, b-i, c-ii, d-iii is the correct match.So, the correct answer is 'a-iv, b-i, c-ii, d-iii'
