iud
hormone pill
condoms
diaphragm

Explanation:

Step1: Understand the Goal

We need to find the contraceptive method with the lowest failure rate (least number of pregnancies per 100,000 women) under typical use (orange bars).

Step2: Analyze the Graph

• IUD (orange bar): Very short, close to 0.
• Hormone Pill (orange bar): Longer than IUD's bar.
• Condoms (orange bar): Longer than Hormone Pill's bar.
• Diaphragm (orange bar): Longer than Condoms' bar.

Step3: Compare the Bars

The shortest orange bar (typical use) is for IUD, meaning it has the lowest failure rate (most effective) under typical use.

Answer:

A. IUD
