in the cytosol of prokaryotes and
the intermembrane space in
eukaryotes
in the cytosol of both prokaryotes
and eukaryotes
in the mitochondrial matrix of
eukaryotes but not in prokaryotes
in the cytosol of prokaryotes and
the mitochondrial matrix of
eukaryotes

Explanation:

Pyruvate dehydrogenase is an enzyme complex that plays a key role in cellular respiration. In eukaryotes, it is located in the mitochondrial matrix. Prokaryotes do not have mitochondria, so this location is specific to eukaryotes.
