Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In angiosperms, the pistil consists of an ovary enclosing one of many ovules. Within ovules, are present highly reduced female gametophytes termed embryo sacs. The embryo-sac formation starts after meiosis (preceded by meiosis). Hence, each of the cells of an embryo-sac is haploid.
So the correct option is A.
