Answer:
b- It is a spontaneous process.
Explanation:
Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.
Substance transport occurs until concentrations inside and outside the cell are equalized.
According to this conceptualization we can conclude that the correct answer to your question is the letter B.

The Correct choice is ~
