Choice A iterates through the array and adds up each element to the variable sum, giving the total number of candy bars sold by the children. Choice B sets each element in the array equal to the variable sum, which does not give the total number of candy bars sold. Choice C sets the variable sum equal to each element in the array, which does not give the total number of candy bars sold. Choice D uses an incorrect syntax of brackets instead of the variable name candy. Choice E also has an incorrect syntax and adds the variable sum to each element in the array instead of adding up all the elements to get the total number of candy bars sold.
