Question

Quizplus · Accepted Answer

Option B creates an integer array called examScore with a size of 4 by using the "new" keyword. This means that the array is instantiated with 4 empty integer slots that can hold exam scores. Option A attempts to declare and instantiate a single integer variable called examScore and set its size to 3, which is incorrect. Option C is similar to option A and sets the size of the integer array to 3, which is also incorrect. Option D attempts to declare and instantiate an integer array called examScores with a size of 4, but appears to be incomplete because it is trying to create an array without any information about the data type of the array.
