Answer:
Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.
Explanation:
The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.
The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.
Thus, the correct answer is option (d).

Answer:
Option B, a generation
Explanation:
A pedigree is a tree diagram that represents the relationships between different individuals based on certain facts and medical(genetic evolutionary) histories. Basically , the branches of the tree represents the generations which allows the researcher understand how certain genetic characteristics or traits are transmitted with in a family
Such as transmission of any genetic diseases from one generation to the other.  
Hence, option B is correct
