Answer:
Correct Answer: C
Solution:
Pinus is monoecious as it bears both types of cones on the same tree on separate branches.
The male cone consists of a number of small spirally arranged microsporophylls.
Each microsporophyll bears two microsporangia or pollen sacs as swellings on the lower surface of its horizontal position.
