Detailed explanation


The right answer is  A) (i) four, (ii) two.

A flower's stamen or male reproductive organ is composed of a stalk-like filament and a knob-like terminal anther.

Each anther contains two lobes connected at the back by a sterile band called the connective.

When both anther lobes are present, the stamen is referred to as bithecous (or dithecous).

A tetrasporangiate dithecous anther has four microsporangia.

Two microsporangia can be found in each lobe, separated by a strap of sterile tissue.

The stamen is referred to as monothecous when only one anther lobe is present.
