b
Ribosomes are found in the cytoplasm of the bacterial cell, and eukaryotes do not have ribosomes.
c
The bacterial cell has both a cell membrane and a cell wall, and eukaryotes have only cell membranes.
d
The bacterial cell is a unicellular organism, and all eukaryotes are multicellular.
a
DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.
The correct answer is:
c
