(A) Pollen viability is the period during which pollen grains remain capable of germinating and fertilizing the ovule.In some cereals like rice ($Oryza$ $sativa$) and wheat,pollen grains lose viability within $30$ minutes of their release.In contrast,in members of some families like $Leguminosae$ (e.g.,pea),$Solanaceae$,and $Rosaceae$,the pollen grains maintain viability for several months.Therefore,the correct sequence for rice and pea is $30$ minutes and several months,respectively.
