Final answer:
The process indicated by 'C' is exocytosis of secretory proteins, where materials like proteins are packaged into vesicles and released outside the cell upon vesicle fusion with the plasma membrane.The right option is C)
Step-by-step explanation:
The process indicated by 'C' described in the student's question is most likely exocytosis of secretory proteins. During exocytosis, materials such as proteins, hormones, and enzymes, are packaged into vesicles within the cell. When these vesicles reach the plasma membrane, they fuse with it and release their contents outside of the cell. This mechanism is crucial for various cellular functions, including the secretion of digestive enzymes by the pancreas, hormone release by endocrine cells, and release of neurotransmitters in the nervous system.
