B. & C.

B. The cell is the most basic structural unit of life. They are independent and can perform processes like excrete waste, take in nutrients etc.
C. There are so many different cell types such as muscle cells, stomach cells, bone, neurons, etc. meaning they “specialize” in one thing such as being a stomach cell.
