Answer:
a. primary oocyte arrested prior to ovulation >> 44 Chromatids
b. spermatozoa >> 23 Chromatids
c. oogonium prior to S phase >> 92 Chromatids
d. secondary polar body >> 23 Chromatids
Explanation:
An immature ovum can be defined as a cell that after oogenesis produces an ovum. The development of an immature ovum involves the following stages: oogonium (46 chromosomes, 2 chromatids), prymary oocyte (46 chromosomes, 4 chromatids), secondary oocyte (23 chromosomes, 2 chromatids), ootid (23 chromosomes, 1 chromatid) and mature ovum (23 chromosomes, 1 chromatid).
The secondary oocyte after the second meiotic division produces a mature ova and a secondary polar body (haploid, 23 chromosomes, 1 chromatid), which generally is not fertilized.
The spermatozoa are male haploid gametes (23 chromosomes, 1 chromatid) developed from germ cells.
