Statement $S$ is false and statement $R$ is true.

Vedclass · Answer

(B) Statement $S$ is false because nucleoprotein ($DNA$ + protein) is a characteristic of viruses,not a general feature of organisms with rigid cell walls. Furthermore,organisms with rigid cell walls (like plants or fungi) have $DNA$ as genetic material,but the term 'nucleoprotein' is specifically associated with viral structure.Statement $R$ is false because the listed organisms belong to different groups: Euglena and Dinoflagellates are Protists,while Amoeba and Paramecium are also Protists,but they do not share a common 'rigid cell wall' characteristic as a defining group feature. Specifically,Amoeba lacks a rigid cell wall. Therefore,both statements are incorrect.
