A large garden has a set of underground sprinklers. Suppose the center of the garden is located at the origin of a grid with intervals measured in feet. One sprinkler is positioned at (2, 4) and reaches a radius of 8 feet. The second sprinkler is positioned at (–6, –4) and reaches a radius of 6 feet. The system of inequalities represents this scenario. Which location is in the region for plants receiving the maximum amount of water?

(–3, –1)
(–7, 1)
(1, –5)
(2, 1)
