The correct option is C Active
Chromatin is a fibrous hereditary material formed by DNA histone complex. Chromatin fibres are of two types: narrow elongated lightly stained transcriptionally active; euchromatin and darkly stained transcriptionally inactive granular; heterochromatin. Thus, the active genes, i.e., the genes which are actively coding for proteins are present in euchromatin. The heterochromatin consists of non-coding genes usually repetitive DNA.
