If an oocyte is fertilized by an x-bearing sperm, the child will be born a with the chromosomal pair of
a. female, xy
b. male, xy
c. male, xx
d. male, it depends on what genetic information the oocyte carries
e. female, xx

e. female, XX

Explanation:

In humans, females are homogametic because they produce only one type of gametes. All the female gametes ( oocyte or ova) have X-sex chromosome. Whereas, human males are heterogametic. they produce two types of gametes. Half of the gametes (sperms) have X-sex chromosome and half of the gametes (sperms) have Y-sex chromosome.  

Therefore, an oocyte or female gamete is fertilized by an X-bearing sperm, the child will be born a female with the chromosomal pair of XX. one X from the male and one X from the female.
