Final answer:
Option 1.
Lake Turkana is a prominent alkaline lake located in Kenya, distinct from other African lakes like Lake Victoria.
Step-by-step explanation:
Lake Turkana is an alkaline lake located in the northeastern part of Kenya.
It is part of the East African Rift System, which is a series of contiguous geographic trenches that stretches from Lebanon's Beqaa Valley in Asia to Mozambique in Southeastern Africa.
Notably, Lake Turkana is the world's largest permanent desert lake and the world's largest alkaline lake. It's also the fourth-largest salt lake by volume in the world, renowned for its unique geographic qualities.
Contrary to certain misconceptions, Lake Turkana is not where the Nile River originates; Lake Victoria claims this distinction.
The Nile River starts from Lake Victoria, flowing through Uganda and Sudan before reaching Egypt. Moreover, Lake Turkana should not be confused with Lake Victoria, which borders Uganda, Tanzania, and Kenya, making it one of the African Great Lakes.
In conclusion, Lake Turkana's significant characteristics—as an alkaline, desert lake within the Great Rift Valley and its location in Kenya—make it stand out among the other prominent African lakes.
Please mention correct option in final answer: The final answer in 20 words is: Lake Turkana, an alkaline lake, is found in Kenya.
