The correct option is:

Option 3) Cu ions released from copper-releasing Intra Uterine Devices (IUDS) suppress sperm motility.

Copper-releasing IUDs work by releasing small amounts of copper into the uterus, which has a spermicidal effect. The copper ions released from the IUD interfere with the motility and function of sperm, reducing their ability to reach and fertilize an egg. This mechanism of action helps to prevent pregnancy.
