B. Americans believed that Carter was weak because he failed to end the conflict quickly.
Explanation:
The Iran hostage crisis refers to a group of angered Iranian radical students who invaded the US embassy and took sixty-six Americans as hostages. Thus, <u>US president Jimmy Carter got the hostages released by paying a ransom of billion dollars, terminating diplomatic relations with Iran and imposing an embargo</u>. Therefore, Americans saw Carter's actions as a signal of weak foreign policy.
