Accepted Answer

A flower that lacks one or more of the four types of modified leaves (sepals, petals, stamens, and carpels) is referred to as incomplete. Therefore, option D is the correct answer. The term perfect refers to flowers that contain both male and female reproductive structures, whereas complete means the flower contains all four types of modified leaves. The term irregular refers to flowers that have unequal shapes, sizes, or arrangements of their petals.
