the only birth control method that is 100% effective in protection from
1 point
unwanted pregnancy and stis is:
abstinence

the birth control pill
withdrawal method

Explanation:

• For the first question, STIs (sexually transmitted infections) can be transferred through vaginal sex, oral sex, anal sex, and sharing needles (e.g., in cases of certain blood - borne STIs like HIV). So all the listed methods are valid transfer routes.
• The birth control pill works by using hormones (usually a combination of estrogen and progestin or progestin - only) to prevent pregnancy. It is not a barrier method (like condoms or diaphragms).
• Abstinence means refraining from any sexual activity. Condoms have a failure rate in preventing pregnancy (albeit low when used correctly) and may not completely prevent all STIs in all cases. The birth control pill only prevents pregnancy and not STIs. The withdrawal method is highly unreliable for preventing pregnancy and does not protect against STIs.

Answer:

• First question: all of the above
• Second question: hormonal contraception
• Third question: Abstinence
