Which of the following is true of carter’s attempt to free the hostages in iran?
carter sought from the united nations.
carter aided the mujahideen in fighting the soviets.
carter opposed a boycott of iranian goods
carter increased trade with the iranians.

I am pretty sure that the following which is true of Carter’s attempt to free the hostages in Iran is the third option represented above. Carter opposed a boycott of Iranian goods. I choose this as a correct one because it refers to the event when American president wasn't stick to his promises and imposed additional sanctions on Iran.
Hope it helps!
