. Microspore mother cell undergoes one meiotic division and gives four microspores.
. Then, the nucleus within the microspore divides mitotically to form one big vegetative nuclei and one small generative nuclei.
. After pollination, the generative cell after entering into the pollen tube divide mitotically to form two non-motile male gametes.
. Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.
So, the correct answer is '1, 2'.
