Answer:

The correct answer is - A. Tight DNA packing tends to promote gene expression.

Step-by-step explanation:

Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.

DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .

DNA packing decreases its transcription and hence no expression.
