Nucleoprotein is the structure when protein is associated with DNA or RNA.
eg ribosome, nucleosome, viral nucleocapsid
DNA + histone protein present in cell nuclei and make a structure called chromatin.
RNP complex = RNA + RNA binding protein
virus capsid is tightly bonded with RNA/DNA
so, the answer is (A)
