The compound that is most likely present when treated with bromine and the sample absorbs the red bromine color is ; Cycloheptene
<h3>What is cycloheptene </h3>
Cycloheptene is an unsaturated colorless oily liquid which is insoluble in water it absorbs Bromine when used in performing unsaturation test due it unsaturated nature.
The red bromine color will be absorbed when used to treat Cycloheptene but will not be absorbed when used to treat cycloheptane due to its saturated nature.
Hence we can conclude that the compound that is present is Cycloheptene.
