The correct answer is option 1, which states that only Kyrgyzstan is in Central Asia. To understand why this is the correct answer, let`s analyze each option:

Option 1: This option suggests that only Kyrgyzstan is located in Central Asia.

Option 2: This option states that Libya and Turkey are in Central Asia, which is incorrect. Libya is actually located in North Africa, while Turkey is situated in both Europe and Asia, with a small portion of its territory in Southeastern Europe (Thrace region).

Option 3: This option claims that Kyrgyzstan and Turkey are in Central Asia, but this is also incorrect. As stated before, Turkey is partially located in Europe and is not entirely in Central Asia.

Option 4: This option suggests that all three countries - Kyrgyzstan, Libya, and Turkey - are in Central Asia, which is not true.

From the analysis above, we can conclude that the correct answer is option 1. The only country listed in the options that is in Central Asia is Kyrgyzstan.
