Solution

The diaphragm is a barrier method of birth control. It is moderately effective, with a one-year failure rate of around 12% with typical use. It is placed over the cervix with spermicide before sex and left in place for at least six hours after sex. Fitting by a healthcare provider is generally required. They may be made from latex, silicone, or natural rubber. They work by blocking access to and holding spermicide near the cervix. The diaphragm came into use around 1882. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. In the United Kingdom they cost the NHS less than 10 pounds each. In the United States they cost about 15 to 75 USD and are the birth control method of 0.3% of people. These costs do not include that of spermicide.

So the correct option is 'contraceptive method- Diaphragms; mode of action- spermicidal and increases phagocytosis of sperms'.
