Expert Answer:

 

As you can see,

In compound (III), due to the formation of the hydrogen bond, its tautomer is most stable.

Because of the less substituted double bond in compound (I), compound (II) is more stable than (I).

Hence the correct order of stability of given tautomeric compounds is III>II>I which means option C is correct.
