Which contraceptive method provides protection for up to three years?

• A. NuvaRing
• B. Levonorgestrel implant
• C. Levonorgestrel intrauterine system
• D. Spermicidal suppositories

Answer: (B)

The concept here is how long different contraceptives provide protection. The levonorgestrel implant is a small subdermal rod that releases hormone steadily over time, giving continuous birth control for about three years. Because it stays in place and works without user action for that period, it fits the “up to three years” protection window precisely. In contrast, other options last longer or require ongoing use: the levonorgestrel intrauterine system can last around five years, which exceeds three; the NuvaRing is used for three weeks at a time and must be replaced monthly; spermicidal suppositories are used at the time of intercourse and do not provide long-term protection.
