{'sperm': [0, 0, 1, 0], 'ovum': [0, 0, 2, 0], 'uterus': [2, 0, 0, 0], 'cervix': [1, 0, 1, 1], 'fallopian tube': [1, 0, 1, 1], 'lower part': [0, 0, 1, 0], 'upper part': [0, 0, 1, 0], 'parts': [6, 2, 8, 19]}
Option 1 is incorrect because the cervix is the lower part of the uterus that connects to the vagina, but it`s not where fertilization occurs.
Option 2 is correct. The fallopian tubes are where sperm must travel after being ejaculated into the vagina. It is here, not inside the uterus, where the sperm will usually meet the ovum and fertilization typically takes place.
Option 3 and 4, the upper and lower parts of the uterus, respectively, are also incorrect. While the fertilized ovum (now referred to as a zygote) will eventually implant itself in the wall of the uterus, the fertilization of the ovum by the sperm typically occurs up in the fallopian tubes, not in the uterus itself.
Hence, the correct answer is option 2, the Fallopian tube.
