The question is based on the concept of organic synthesis.We need to synthesize the product using reactants and reagents provided.In the first step, we use acidic solution of sodium chromate so that alcohol gets oxidized into corresponding carboxylic acid..Next, we use sodium borohydride so that ketone gets reduced to corresponding alcohol. Sodium borohydride is a weak reducing agent which does not reduce carboxylic acid.Finally, under acidic conditions intramolecular nucleophilic acyl substitution takes place and lactone is formed.
