Solution

The correct option is C (i) Br2,hv; (ii) t-butoxide; (iii) BH3,THF;H2O2,OH

The sequence of reagents required to accomplish the given transformation is
(i) Br2,hv; (ii) t-butoxide (iii) BH3,THF;H2O2,OH

First step is the replacement of H atom of alkane with Br atom to form alkyl bromide. Second step is dehydrobromination to form alkene. Third step is hydroboration oxidation to form primary alcohol.
