The correct option is C Stamens are within the corolla
∙ Wind pollinated flowers are unisexual, dull-coloured and hold very little or no fragrance and nector. In the case of female flowers, the stigma is long and hangs out of of the petals. It is feathery or sticky to trap the pollen grains. In the case of male flowers, the stamens are long and hang out of the corolla tube to be exposed to wind so that they could be carried away by it. The stamens of wind pollinated flowers are not in an enclosed setting.
