What is the output of the following code:
my_string = "Hello, World!"
print(my_string.split())

The correct answer is Option B: ['Hello', 'World!']. Here's the explanation:
When you use the split() method on a string without passing any arguments, it splits the string by whitespace characters (space, tab, newline, etc.) and returns a list of the resulting substrings.
In the given code, my_string.split() will split the string "Hello, World!" by whitespace characters and return a list containing two elements: "Hello" and "World!".
Therefore, the output will be ['Hello', 'World!'].
