Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Ribosomes are the only cell organelles found in both prokaryotic and eukaryotic cells. Reason (R): Prokaryotic cells lack membrane-bound organelles, and ribosomes are not bound by any membrane. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Assertion (A) is true because ribosomes are the universal organelles present in all living cells, both prokaryotes and eukaryotes. Reason (R) is also true and correctly explains the assertion. Prokaryotes are defined by the absence of a well-defined nucleus and membrane-bound organelles (like mitochondria, Golgi bodies, etc.). Since ribosomes are non-membrane bound, they are the only organelles that can exist in the prokaryotic cytoplasm while also being present in eukaryotes. Answer: Both Assertion and Reason are
