According to the text, which of the following statements correctly differentiates between the use of condoms and diaphragms as contraceptive methods?

  • A: Condoms are less effective in preventing pregnancy than diaphragms when used with spermicides.
  • B: Diaphragms are the only barrier method highly effective in preventing sexually transmitted infections (STIs).
  • C: Condoms are effective in preventing STIs, whereas diaphragms offer lower pregnancy rates primarily when used in conjunction with a spermicidal agent.
  • D: Both condoms and diaphragms are placed over the penis to collect semen.

Explanation

The text states that 'latex condoms are the only contraceptives that are highly effective in preventing the spread of AIDS and other sexually transmitted infections STIs '. It also notes that the 'diaphragm, a dome-shaped rubber cap inserted into the upper portion of the vagina... have lower pregnancy rates when used in conjunction with a spermicidal sperm-killing foam or jelly.' This directly supports option C.
