Dear student,
Meiotic divisions are responsible for gamete formation. For wheat or any other flowering plant it is necessary to have a pollen ( 4 after one meiotic division) and an egg cell ( usually one after one meiotic division) to produce a single seed.
To produce a 80 wheat grain there should be 80 meiotic divisions to produce 80 egg cells. And 20 divisions to produce 80 pollen grains. So total 100 meiotic divisions are required to produce 80 wheat grains.

Option 1 is correct
