Solution

The correct option is E III and VII
Sepals (VI) and petals (I), are parts of accessory whorls of a flower and serve to attract pollinators only. A stamen consists of anther (III) and filament (IV). Anther is a broad knob part of stamen, that contains two long and cylindrical microsporangia in its lobes. Carpel is the female part of flower, derived from central region of thalamus and consists of stigma (II), style (V) and ovary (VII). Ovary and anther, are site of meiosis in flower to produce microspore (pollen) and egg cell respectively. So, the correct answer is option E.
