Correct Answer: Option B — 1 and 3 only
Here is why:

Statement 1 is correct: Lake Turkana is indeed the world's largest permanent desert lake (and the world's largest alkaline lake).

Statement 2 is incorrect: The lake is located primarily in northern Kenya, with its northernmost tip crossing into Ethiopia. It is not in South Sudan, nor is it along the Sahara desert (it lies in the East African Rift Valley).

Statement 3 is correct: It is famously nicknamed the "Jade Sea" due to its breathtaking turquoise-green color (caused by algae). The Lake Turkana National Parks are also listed as a UNESCO World Heritage Site.
