The following question has four items. Select the item that does not belong to the group.

Step-by-step solution

Here in the question, we have to find the word which is the odd one out among the given four. Here propitiate, conciliate and appease are synonyms of each other and have the same meaning i.e. to stop someone from being angry by doing something to please them or to bring into an agreement. Whereas, appreciate means to admire and value someone or something. Hence, appreciate has a different meaning from others, so appreciate is the odd one.
