Placentation found in caryophyllaceae is
In the family Caryophyllaceae, the gynoecium can have two to five carpels and these carpels are essentially fused, so the ovary is syncarpous. However, the styles and stigma remain free. The ovary is unilocular and shows free-central type of placentation. In this type, the ovules are arranged on the central axis which is not attached to the wall of the ovary by any septum. The ovules are campylotropous. Hence, the correct answer is 'Free-Central'
