Answer»

Right option is (b) Eukaryotes

The best I can explain: Cistrons are the segments of the DNA HELICAL STRUCTURE which code for polypeptide chains. The structural gene in the transcription UNIT can be either monocistronic or POLYCISTRONIC. The monocistronic genes are mostly present in eukaryotes.
