The correct option is A Packed in pollinia
The Asclepiadaceae are mostly herbs and shrubs with white sap comprising about 250 genera and 2000 species, many of which are lianous and some of which are cactus like succulents with reduced leaves. The anthers usually produce paired sacs of pollen called pollinia, that are transferred as a unit during pollination. These pollinia are arranged in three different ways: Erect, horizontal and pendulous.
