Consider the following countries:

1. Azerbaijan
2. Kyrgyzstan
3. Tajikistan
4. Turkmenistan
5. Uzbekistan

Which of the above have borders with Afghanistan ?

The correct option is 3, 4 and 5 only (Tajikistan, Turkmenistan, and Uzbekistan).

To understand why this is the correct answer, we can analyze the geographical borders of Afghanistan with each of the countries listed in the question:
1. Azerbaijan: Located in the South Caucasus region, bounded by the Caspian Sea and Russia, Georgia, Armenia, and Iran. It does not share a border with Afghanistan.
2. Kyrgyzstan: A landlocked country in Central Asia, bordered by Kazakhstan, Uzbekistan, Tajikistan, and China. It is separated from Afghanistan by Tajikistan (specifically the Wakhan Corridor region). Thus, it does not share a border with Afghanistan.
3. Tajikistan: Shares a long border with northeastern Afghanistan, stretching approximately 1,357 kilometers along the Panj and Pamir rivers.
4. Turkmenistan: Shares a border with northwestern Afghanistan, spanning approximately 804 kilometers.
5. Uzbekistan: Shares a short border with northern Afghanistan, approximately 144 kilometers long, running along the Amu Darya river. The Friendship Bridge connects the two countries between Termez and Hairatan.

Therefore, among the given list, only Tajikistan (3), Turkmenistan (4), and Uzbekistan (5) share borders with Afghanistan.
