Answer & Solution
Correct answer: B. every cell has one nucleus + one mitochondrion
Cell theory has three claims: organisms are cellular, cell is the basic unit, cells come from cells. Fixed counts of organelles per cell are NOT part of the theory; mature red blood cells have no nucleus, and some cells have hundreds of mitochondria.
