To determine the best location for early settlers to establish a settlement based on needs such as farming and fishing, you'd typically look for a place with access to fresh water, fertile land, and proximity to the coast or rivers for fishing. However, without specific details or maps associated with the options A, B, C, and D, I cannot provide a definitive answer.
If you could provide descriptions or characteristics of each location, I would be better positioned to identify which one would likely be best for early settlers.
