      Chasmogamy is a botanical term describing a type of flower. A chasmogamous flower opens at maturity, exposing stamens and style to allow fertilization. The flower undergoes cross-pollination. Chasmogamous flowers also provide pollen to other plants.

      so according to me more preferable ans is cleistogamous flower
