The correct answer is D) water.
The resource that became an important issue in Florida in the 1800s due to an increase in settlers was water.
At the beginning of the 1800s, Spanish people offered many benefits to settlers to come to Florida. Abundant land and water were what Spain offered. It needed to be populated to start working in the land and produce goods for the benefit of Spain.
But as time went by, the resource that became an important issue in Florida in the 1800s due to an increase in settlers was water. This means that when Florida's population grew, they demanded more natural resources. Water from the swamps was not for drinking. So people used fresh water for drinking, bathing, and they used water for farming. So they consumed a lot of the vital liquid. That is why the resource that became an important issue in Florida in the 1800s due to an increase in settlers was water.
