The correct answer is B.Endocytosis.

Endocytosis is the active transport process in which cells move proteins (or other substances) into the cell by engulfing them in a vesicle made from the plasma membrane. This process requires energy (ATP) and is used to take in large molecules, like proteins, into the cell.

Here’s a breakdown of the other options:

A.Facilitated Diffusion: This is a passive transport mechanism where molecules move across the membrane through protein channels or carriers, but it does not require energy and does not involve vesicle formation.
