Answer is Wrong!
Answer is Right!
The correct answer is C. 11.
The IndexOf method returns the index of the first occurrence of a specified string within a string. In this case, the string “TN” is found at index 11, so the IndexOf method returns 11.
Option A is incorrect because the IndexOf method returns an integer, not a Boolean value.
Option B is incorrect because the IndexOf method does not return False if the specified string is not found.
Option D is incorrect because the IndexOf method returns the index of the first occurrence of the specified string, not the last occurrence.
