GPT-4:

In Africa, there are three countries that start with the letter "K":

1. Kenya
2. Kingdom of Eswatini (although it's often referred to simply as Eswatini)
3. Kiribati

However, it's worth noting that Kiribati is not in Africa; it's a Pacific island nation. So, only Kenya and the Kingdom of Eswatini in Africa start with the letter "K", but most people just refer to Eswatini without the "Kingdom" prefix. If you meant countries solely with the prominent "K" at the start, then it's just Kenya.

Anecdotal evidence is useless because it can be contradicted with anecdotal evidence.
