The correct option is C smooth ER
Endoplasmic reticulm (ER) are of two types - smooth ER (SER) and rough ER (RER).
Smooth ER does not possess ribosomes on the surface. It is the major site for synthesis of lipid. In animal cells, lipid-like steroidal hormones are synthesised in SER.
Rough ER have ribosomes on the surface. Due to the presence of ribosomes, it is actively involved in protein synthesis and secretion.
Golgi complex mainly performs the function of packaging materials (proteins), to be delivered either to the intra-cellular targets or secreted outside the cell.
