ovary wall is also called as pericarp. the pericarp is the part of fruit enclosing the seeds that develop from the wall of the ovary. double fertilization is the characteristic feature of angiosperms, where triple fusion takes place and results in the formation of  triploid endosperm for nourishing the zygote formed by fusion of male gamete with the egg cell, a process called double fertilization. dormancy is a mechanism, to prevent germination during unsuitable environmental conditions when the probability of seedling survival is low. endosperm formed in the ovule provides nourishment for the growing embryo. it gets depleted by the time embryo grows up to a seedling.  
so, the correct answer is option b.
