Solution
The correct option is B Cleavage polyembryony
The separation of the zygote into a number of smaller units, which undergo competition with each other is called as cleavage polyembryony, to distinguish it from the simple polyembryony, that may result from the fertilization of several eggs. The free nuclear divisions occurring during the proembryo stage in Pinus are followed by the equal cleavages, which organize the initial cells of each of the embryos, that separate. It is well known, that only one of these many embryos, produced either by cleavage polyembryony or by simple polyembryony survives to the maturity of the seed.
