Solution

The correct option is C The ovulated egg released during pregnancy dies.
Pregnancy occurs as a result of fertilization of the mature egg (which is released during ovulation, menstrual cycle) and the sperm.
Hence, option C is incorrect - the ovum does not die during pregnancy as it has been fertilized by the sperm, thereby forming zygote.
Therefore, the correct answer is option C.
