CENTO stands for:

CENTO stands for the Central Treaty Organization. This was a military alliance formed during the Cold War era, originally known as the Baghdad Pact, established in 1955. Its primary objective was to prevent Soviet expansion into the Middle East by creating a defensive barrier. Member states included the United Kingdom, Iran, Iraq, Pakistan, and Turkey, with the United States participating as an associate member. The organization was dissolved in 1979 following the Iranian Revolution and Iraq's earlier withdrawal. The other options are incorrect because CENTO was fundamentally a military and defense pact, not focused on economic, European, or intelligence treaties, despite intelligence sharing occurring within its framework.
