Solution

The correct option is B Abaxially
Microsporangia of Cycas occur over microsporophyll abaxially. Microsporophyll bear sort of sporangia on the abaxial surface, because the terminal portion is sterile. Cycadophyta are typically dioecious. The lateral organs of seed strobili are megasporophylls (modified leaves), that bear two to several marginal ovules. Pollen strobili consist of microsporophylls, each of which may have dozens or hundreds of abaxial microsporangia.
