FSH and LH
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are hormones involved in the human reproductive process, controlling sexual development and function.
Implantation
The process by which a fertilized egg attaches to the lining of the uterus to begin pregnancy.
Corpus Luteum
The corpus luteum is a temporary endocrine structure in female ovaries that is involved in the production of relatively high levels of progesterone, some estrogens, and other hormones during the menstrual cycle.

Final Answer :
C
Explanation :
Preven, the morning-after pill, works by preventing implantation of the embryo in the uterus. Implantation usually occurs around the third day after fertilization. Therefore, Preven can be taken over the period of one to three days after unprotected sex to prevent implantation and ultimately prevent pregnancy.
