A Correct answer
Explanation

Prokaryotes (bacteria) lack histones - their DNA is 'naked' and not organized into nucleosomes like eukaryotic DNA. Eukaryotes wrap DNA around histone proteins to form chromatin, while prokaryotes have simpler, unprotected DNA. Protozoa are eukaryotic and have histones, making them incorrect.
