The correct answer will be option-those that contain inactive genes.

Explanation:

The chromatin of the chromosome can be classified into two types: euchromatin and heterochromatin on the basis of the level of the compaction.

The part of the chromatin which is transcriptionally active is loosely arranged so that enzymes can act and forms the euchromatin portion of the chromatin while the part of the chromosomes which is transcriptionally off become tightly packed and forms the heterochromatin.

Since the more compact region is represented by the heterochromatin, therefore, the option-those that contain inactive genes is the correct answer.
