A Correct answer
Explanation

index($string, "cd", 3) searches for cd starting from position 3 in abcdabcd. Positions 0-7: abcdabcd. From index 3, the next cd starts at index 6 (second cd). index returns the position where substring is found, making option A correct. Starting position 3 means it skips the first cd at position 2.
