The following is intended to count the number of times the number 100 is found in an array of test scores:

int [ ]d = /* Assume array is correctly initialized */ ;
int perfect = 0;
for (int i = 0; i < ; i++)
{
if ( /* missing code */ ))
perfect++;
}
System.out.println("Number of perfect scores: " + perfect);
Which of the following could replace /* missing code */ so that the code works as intended?
