C) amoeboid motion
D) positive chemotaxis

Accepted Answer

The process by which white blood cells move in and out of blood vessels is called diapedesis or extravasation. This is a vital process that allows white blood cells to get to the site of infection or injury and carry out their immune functions. Diffusion and amoeboid motion refer to other forms of cellular movement, while positive chemotaxis refers to the directional movement of cells in response to chemical signals.
