Consider the following incomplete method, which is intended to return the longest string in the string array words. Assume that the array contains at least one element. public static String longestWord(String[] words)
{
/* missing declaration and initialization */
for (int k = 1; k < words. length; k++)
{
if (words[k].length() > longest. length())
{
longest = words[k];
}
}
return longest;
}

Which of the following can replace /* missing declaration and initialization */ so that the method will work as intended?

a. int longest = 0;
b. int longest = words[0].length();
c. String longest = "";
d. String longest = words[0];
e. String longest = words[1];
