Solution

The correct option is A Processing of hnRNA
The processing of hnRNA takes place in the nucleus as it is the last step of transcription process which occurs inside nucleus whereas DNA is held while activation of amino acids, translation, and formation of polypeptide chain takes place in the cytoplasm of cell where ribosomes are present as ribosomes are the sites on which protein synthesis takes place.
Activation of amino acids, translation, and formation of a polypeptide chain takes place outside the nucleus.
Thus, the correct answer is option A.
