Select the code for the correct answer from the options given below.

Two of the following statements are correctly defined. Identify the correct combination

i) Conversion of hnRNA to mRNA - processing

ii) Removal of introns and joining of exons - splicing

iii) Addition of adenylate residues to $3\text{'}$- end in a template dependent manner - Tailing

iv) Methyl adenosine triphosphate is added to $5\text{'}$ - end of hnRNA - capping
