Answer:
A. Active transport requires cell energy while osmosis does not
Step-by-step explanation:
Active and passive transport are important for living organism as they regulates the entry and exit of molecules and ions in a cell.
Active transport require cell energy in the form of ATP to maintain the right concentrations of ions and molecules in living cells while osmosis is a type of passive transport and doe snot require cell energy this is so because ion concentrations in osmosis remain same both the side of the membrane and do not require cell energy to pump the molecules.
Hence, the correct answer is "Active transport requires cell energy while osmosis does not".
