Solution
The correct option is A Heterochromatin
Euchromatin or loosely packed chromatin
Euchromatin is the lightly stained and loosely packed region of chromatin fibre and forms the bulk of chromatin. It is transcriptionally active as it takes part in the process of transcription to form mRNA.
Heterochromatin
Heterochromatin is the darkly stained and highly condensed region of chromatin fibre and is present only at certain places in the chromatin structure. It is the transcriptionally inactive chromatin as it cannot be transcribed to form a mRNA.
Final answer
(B) Heterochromatin
