Of the following, which is the product formed when cyclohexanone undergoes aldol condensation followed by heating?

Cyclohexanone reacts with another molecule of itself in the presence of a base.Formation of enolate ion from one cyclohexanone molecule.Nucleophilic attack on the carbonyl carbon of the second cyclohexanone molecule.Dehydration (removal of water) upon heating to form an $\alpha ,\beta$ -unsaturated ketone.The resulting product is 2-(cyclohex-1-en-1-yl)cyclohexanone (often referred to as cyclohexylidenecyclohexanone).
