Solution

The correct option is B Both assertion and reason are true but reason is not the correct explanation of assertion
In eukaryotes, transcription occurs in the nucleus to produce a pre-mRNA molecule. The pre-mRNA is typically processed to produce the mature mRNA, which exits the nucleus and is translated in the cytoplasm.

In prokaryotes, the mRNA does not require any processing to become active. Hence transcription and translation takes place in the same compartment i.e cytoplasm.
