SSCE VCE Biology Cell Structure and Function: Early experiments to investigate

Question

Early experiments to investigate cell functioning used amoeba (Amoeba proteus). An amoeba is a relatively large, single-celled organism. It is possible to bisect an amoeba to produce half with the nucleus and the other half without a nucleus (enucleated).  
The following diagram shows the results.

The most likely reason for the enucleated half-cell to die after seven days is that:  
A. water was lost by osmosis.  
B. protein synthesis was reduced.  
C. the fluidity of the membrane was lost.  
D. no mitochondria were in the enucleated half-cell.
