Answer: option B - dioecious; imperfect
Explanation:
Dioecious refers to plants species having the MALE and FEMALE reproductive organs on SEPARATE plants (of the same species) rather than different parts of the same plant.
That is to say, a plant species has its male-flowering plant at point A, while its female-flowering plant grows at another point B. Hence, male and female organs are NOT present on the same flower making it IMPERFECT.
