When the condition in an If statement evaluates to true, the code block or the action that is associated with that If statement is executed. This means that whatever instructions are contained within the curly braces following the If condition will run. For example, if the condition checks whether a variable is equal to a specific value and that condition holds true, the program will perform the actions defined within that If block, which could be anything from changing a variable's value, calling a function, or printing output.

Understanding this fundamental behavior of If statements is crucial because it illustrates how decisions are made in programming. Each If statement can influence the flow of the program, allowing for conditional execution based on varying inputs or states in your program.
