Explanation:

Step1: Identify countries with literacy rate >90%

Check each country's rate:

• Argentina: 98% >90%
• Cuba: 100% >90%
• Mali: 33% <90% (exclude)
• Pakistan: 55% <90% (exclude)
• Poland: 100% >90%
• Saudi Arabia: 87% <90% (exclude)
• Spain: 98% >90%
• Turkey: 94% >90%
• United States: 99% >90%

Step2: Match with options

Check each option:

1. Argentina, Cuba, Poland, United States: Missing Spain, Turkey? Wait, no—wait the option we need is the one that includes all above 90%. Wait, let's re - check the options. Wait the last option: Cuba, Poland, United States, Argentina, Turkey, Spain. Let's verify each in this option:

• Argentina: 98% >90%
• Cuba: 100% >90%
• Poland: 100% >90%
• United States: 99% >90%
• Turkey: 94% >90%
• Spain: 98% >90%

Now check other options:

• First option: Argentina, Cuba, Poland, United States—missing Spain, Turkey.
• Second option: Cuba, Poland—missing others.
• Third option: Argentina, Saudi Arabia (87% <90%, so wrong), Cuba, Poland, United States—Saudi Arabia is wrong.

So the last option (Cuba, Poland, United States, Argentina, Turkey, Spain) includes all countries with literacy rates above 90%. Wait, but let's check the original options again. Wait the user's options:

Option 1: Argentina, Cuba, Poland, United States

Option 2: Cuba, Poland

Option 3: Argentina, Saudi Arabia, Cuba, Poland, United States

Option 4: Cuba, Poland, United States, Argentina, Turkey, Spain

Argentina: 98% >90%

Cuba: 100% >90%

Poland: 100% >90%

United States: 99% >90%

Spain: 98% >90%

Turkey: 94% >90%

Saudi Arabia: 87% <90%

Mali: 33% <90%

Pakistan: 55% <90%

So countries above 90%: Argentina, Cuba, Poland, United States, Spain, Turkey.

Now check option 4: Cuba, Poland, United States, Argentina, Turkey, Spain—this includes all of them.

Other options:

Option 1: Missing Spain, Turkey.
