The correct answer is: $(+)$ butan-2-ol and (-) butan-2-ol
$d$-and $l$-isomers (enantiomers) have identical
chemical and physical properties. They are indistinguishable from each other except for the direction of rotation of the plane polarised light. Thus ( + ) butan-2-ol and (-) butan-2-ol will have same boiling points.
