A Correct answer
Explanation

Option A is the simplest approach if 'im' is already a reference to the 50th element. The question asks for the simplest code snippet to add, and directly setting the name attribute with 'im.name = "Done";' is the most concise. Option C is more explicit but verbose - it retrieves the element and sets the name in one statement, which is self-contained but not the 'simplest' to add if im already exists.
