Answer:
Option A, Spermatozoa can generally be found in the vagina of a living female after three days
Step-by-step explanation:
The average life of spermatozoa in the female reproductive tract after ejaculation determines the fertility. Sperm survive for a longer period of time after it reaches the cervix. A spermatozoon (motile sperm) survives for nearly 2.5 hours in the vagina and 48 hours in the oviduct.
However, spermatozoa irrespective of its motility or viability can be found after coital ejaculation in the cervix and vagina even after 12 and 9 days respectively.
Hence, option A is the correct choice of answer
