Solution

The correct option is B Gynodioecious
In plants like Beta vulgaris, the gynodioecious condition is seen in which some plants have bisexual or hermaphroditic or perfect flowers. These flowers have both the male sex organs (androecium) and female sex organs (gynoecium). Then there are some plants that have only the pistillate or female flowers. A population of plants belonging to a species in which there is a co-existence of bisexual and pistillate flowers is called gynodioecious.
Hence, the correct answer is 'Gynodioecious'.
