• B. the ovum and sperms are transported simultaneously to ampullary–isthmic junction of the cervix
• C. the ovum and sperms are transported simultaneously to the ampullary–isthmic junction of the Fallopian tube
• D. the sperms are transported into vagina just after the release of ovum in Fallopian tube

Answer 1

The correct option is C

the ovum and sperms are transported simultaneously to the ampullary–isthmic junction of the Fallopian tube

The correct option is C.

2. The ampullary area of the fallopian tube or oviduct is where fertilization takes place.
3. The ovum and sperms must be transferred to the ampullary–isthmic junction of the Fallopian tube at the same time for fertilization to take place.
