Solution

The correct option is B Reaction with R-Mg-I, hydrolysis/ $H^{+}$
During the conversion of lower secondary alcohol to higher tertiary alcohol,
the intermediate ketone should undergo the following reactions:
Reaction with R-Mg-I, hydrolysis/ $H^{+}$
Ketone reacts with Grignard reagent and gives tertiary alcohol.
Hence option A is correct
