Fertilization in humans is practically feasible only if:

  1. A
    The ovum and sperms are transported simultaneously to ampullary – isthmic junction of the fallopian tube
  2. B
    The ovum and sperms are transported simultaneously to ampullary – isthmic junction of the cervix
  3. C
    The sperms are transported into cervix within 48 hrs of release of ovum in uterus
  4. D
    The sperms are transported into vagina just after the release of ovum in fallopian tube

Solution & Step-by-step Explanation

Fertilization occurs in the ampulla region (often described as the ampullary-isthmic junction) of the fallopian tube. It can only occur if the ovum and sperm are present there at the same time.
