Explanation:

• Spermicide is a chemical that kills sperm but is not a disc - shaped device.
• Birth - control pills are oral medications, not inserted into the vagina.
• A contraceptive sponge is a soft, round, disposable device that contains spermicide and is inserted into the vagina before sexual intercourse.
• A diaphragm is also a barrier method but is a rubber dome - shaped device (not disc - shaped polyurethane in the context of this description as much as the sponge which is more likely to be described as disc - shaped in some cases and with the given material). However, the contraceptive sponge is a disc - shaped (more like a flat round shape) polyurethane device with spermicide inserted into the vagina.

Contraceptive sponge
