To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.

Answer: Option B) Nuclei house the DNA, which is the blueprint for proteins. Cell types I, II, and III can synthesize proteins. 
Explanation:
All the genetic information that determines the traits expressed in an organism are loaded up within the DNA sequence. Hence, several genes that codes functional proteins are derived from the DNA, making DNA a blueprint for protein synthesis. 
Thus, Cell types I, II, and III with DNA can synthesize proteins. 
 
        
                    
             
        
        
        
The main role of chloroplasts<span> is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water</span>
