• A. I, II
• B. I and IV
• C. III, IV
• D. II, IV

Answer 1

The correct option is B I and IV

Dioecious is the condition in which each plant bears only single type of flower either male or female. There are male flower producing plants and female flower producing plants separately.eg:date palm.
Marchantia is dioecious, hence male and female sex organs are produced on separate plants. The male sex organs are called antheridia, and the female sex organs as archegonia.
