The value that will be returned when the code is executed is 5.
Explanation: The array "prime" is initialized with four integer values - 2, 3, 5, and 7. Each of these values is assigned an index starting from 0. Therefore, the value at index 2 of the array "prime" is 5. When prime[2] is called, it returns the value at index 2 of the array which is 5.
