Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Cells actively engaged in protein synthesis possess smaller and fewer nucleoli. Reason (R): The nucleolus is the site for active ribosomal RNA (rRNA) synthesis. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Assertion (A) is not correct. According to NCERT, cells that are actively engaged in protein synthesis possess larger and more numerous nucleoli to meet the high demand for ribosomes. Reason (R) is correct. The nucleolus is the site for active ribosomal RNA (rRNA) synthesis. Therefore, Assertion (A) is not correct but Reason (R) is correct. Answer: Assertion (A) is not correct but Reason (R) is correct
