If the reactant is cis isomer than following reaction takes place. Solution Image

i.e. two isomers are produced. If the reactant is trans isomer than following reaction takes place. Solution Image

i.e. only 1 isomer is produced. Thus, statement (I) and (III) are correct resulting to option (b) as the correct answer.
