Pls answer and explain this que .......?o ,o

Solution:

The correct option is (a).
Gnetum is a gymnosperm that has similarities with angiosperms. At the same time, it also shows differences with other groups such as Cycas and Pinus.

Affinities of Gnetum with the angiosperms:

• It has broad, green leaves with reticulate venation.
• Archegonia are altogether absent in the female gametophyte.
• There is no free nuclear division in the embryo sac.
• The development of endosperm is completed after the fertilization.
• Xylem vessels are present

All these similarities make Gnetum identical to angiosperms and separate it from other gymnosperms like Cycas and Pinus.
