a. after the egg attaches to the wall of the uterus
b. while the egg is being released through the vagina
c. after the egg is released from the ovaries
d. while the egg is developing in the ovaries

Explanation:

• Option A: After the egg attaches to the uterine wall (implantation), it is already part of early pregnancy, not the fertilization stage.
• Option B: When the egg is released through the vagina (menstruation), it is unfertilized and being shed.
• Option C: After ovulation (egg release from ovaries), the egg travels through the fallopian tube, and sperm can fertilize it there.
• Option D: While the egg is developing in the ovaries, it is not yet ready for fertilization.

Answer:

C. After the egg is released from the ovaries
