Correct Answer - D
500 seeds of pea would be produced from 200 pollen grains and 200 embryo sacs. 200 pollen grains will be formed by 50 microspore mother cells, while 200 embryo sacs will be formed by 200 megaspore mother cells. Similary 400 seeds of pea would be produced from 400 pollen grains and 400 embryo sacs. 400 pollen grains will be formed by 100 Microspore Mother Cell (MMC) and 400 embryo sacs formed by 400 Megaspore Mother Cell (MMC). Thus, number of meiotic divisions required to produce `200//400` seeds would be `250//500`.
