The fully processed hnRNA is called (i) and is transported out of the (ii) into (iii) for translation.

Solution
The correct option is A (i) mRNA, (ii) Nucleus, (iii) Cytoplasm Heterogeneous nuclear RNA or hnRNA is a term that encompasses various types and sizes of RNAs found in the eukaryotic cell nucleus. When this undergoes modifications and processing it will give rise to the mature mRNA that has the inherent code for the protein synthesis (amino acid code). The mRNA in eukaryotes is synthesized in the nucleus and hence should be transported to the cytoplasm and into the ribosome for protein synthesis by the process of translation.
So, the correct option is '(i) mRNA, (ii) Nucleus, (iii) Cytoplasm'.
