What is a benefit of using TFIDF instead of just term frequency in text mining?

a. TFIDF can be used in a bag-of-words approach, but term frequency cannot.

b. TFIDF is a normalized measure that accounts for the varying lengths of documents in a corpus, but term frequency is not.

c. TFIDF considers how often a term occurs in a document as well as how rare it is in the other documents of the corpus while term frequency only considers how often a term occurs.

d. TFIDF can be used in word clouds, but term frequency cannot.
