Given below are four statements pertaining to fertilization in human beings. Identify the correct statement.

I. Fertilisation can occur if the ovum and the sperms are transported simultaneously to the ampullary region of the Fallopian tube.

II. The secretion of the acrosomes helps the sperm enter the cytoplasm of the ovum.

III. The completion of the meiotic division of the secondary oocyte is induced by the entry of sperms into it.

IV. Hyaluronidase secreted by the acrosomes ensures that only one sperm can fertilise the ovum.
