Meiotic division of the secondary oocyte is completed:

  3. C
    After zygote formation
  4. D
    At the time of fusion of a sperm with an ovum

Solution & Step-by-step Explanation

The secondary oocyte completes its second meiotic division only at the time of fusion of a sperm with an ovum. This entry of the sperm induces the completion of meiosis II, resulting in the formation of a second polar body and a haploid ovum (ootid).
