Solution
The correct option is A Red blood cells
In humans, the RBCs lack mitochondria, since all the space inside the cells is used for haemoglobin. Thus, the glucose in RBCs is broken down anaerobically to lactic acid in absence of mitochondria.
All other cells have mitochondria and there is anaerobic respiration only during the absence of oxygen.
