Total number of intramolecular aldol condensation products possible from given compound is (excluding stereoisomer).

Aldol condensation is an organic reaction in chemistry where an enol or enolate ion reacts with a carbonyl compound to form β- hydroxyaldehyde or β-hydroxyketone followed by dehydration to form conjugated enone. It is of two types intramolecular and intermolecular.

For the given molecule, three possible aldol condensation is present.

1)

2)

3)

There are three possible aldol condensation possible.

Therefore , the correct answer is $3$.
