Suppose we want to remove all duplicate words (words are separated with single whitespace) in a line, which is accepted by the user. The following code is written to do that. Choose the correct observation based on the code.

s = raw_input()

words = [word for word in s.split()]

print ” “.join(set(words))

A

The code works fine.

B

Instead of print ” “.join(set(words)) it should be print ” “.join(list(words)) to make the code work correctly.

C

Instead of words = [word for word in s.split()] it should be

words = s.split() to make the code work correctly.

D

Instead of print ” “.join(set(words)) it should be print ” “.join(dict(words)) to make the code work correctly.
