Which of the following statements about the following code is false? word_counts = {}
For word in text.split():
If word in word_counts:
Word_counts[word] += 1
Else:
Word_counts[word] = 1
A) The expression text.split() xe "tokenize a string"tokenizes text by calling string method split, which separates the words using the method's delimiter string argument-if you do not provide an argument, split uses a space.
B) Method split returns a list of tokens (that is, the words in text).
C) The expression word_counts[word] += 1 inserts a new key-value pair in the dictionary.
D) All of the above statements are true.

A) The first statement is true as text.split() tokenizes the string into words using whitespace as delimiter.
B) The second statement is true as method split returns a list of words.
C) The third statement is false because the code is not inserting a new key-value pair; it is updating the value for an existing key in the dictionary. If word is already in the dictionary, then the if statement is true and the code increments the value associated with that key (i.e., word_counts[word] += 1). If word is not already in the dictionary, then the else statement is executed and a new key-value pair is added to the dictionary with a value of 1 (i.e., word_counts[word] = 1).
