Solution

The correct option is C Propane
In presence of as KOH, 2, 2-dichloropropane is hydrolyzed to propane-2,2-diol which loses a molecule of water to form acetone (compound A). Clemmensen
reduction of acetone (in presence of Zn/Hg and conc HCl) gives propane (compound B). A carbonyl group is reduced to methylene group.
