Question

us intervention in iran in the 1950s
inspired future democratic elections.
led to continued us support of iranian nationalists.
led to the islamic revolution of 1978.
was opposed by the british government.

Explanation:

The US intervention in Iran in the 1950s, specifically the 1953 coup (Operation Ajax), overthrew the democratically - elected Prime Minister Mohammad Mosaddegh. This intervention created a sense of resentment and instability in Iran. The Shah of Iran, who was reinstalled with US support, ruled in an autocratic way. This autocratic rule, along with other factors, contributed to the dissatisfaction that led to the Islamic Revolution of 1978 - 1979.

• The US intervention was not about promoting democratic elections. In fact, it overthrew a democratically - elected leader.
• After the intervention, the US supported the autocratic Shah, not Iranian nationalists (Mosaddegh was a nationalist).
• The British government was a part of the intervention (it was a joint UK - US operation).

Answer:

led to the Islamic revolution of 1978.
