Identify the transport mechanism: a passive process that uses a pressure difference as its driving force:
a. atp-driven pumps
b. diffusion
c. filtration
d. facilitated diffusion

The correct option out of the four given options is

option C. filtration

Explanation:

ATP - driven pumps are not used for passive transport these are used for primary active transport

Diffusion does not depend on pressure difference they depend on the differences in concentrations.

Filtration is that mechanism of transport in a passive process in which the driving force is provided by pressure differences or pressure gradient.

In facilitated diffusion glucose is made to pass the membrane with the help of integrated protein in the membrane. it is a passive process.
