Choose the odd one out from the given group of words:
 

• In the given question, we've been given four options and we have to find the odd word from the given words. An odd word refers to a word that doesn't fit the common meaning that exists among the given words.
  In order to seek out the odd word, allow us to understand the meanings of the given words.
• The first word, graceful, means being elegant in action or form . The second word, beautiful, means attractive or pretty.  The third word, awkward, means not convenient or difficult. The fourth word, decent, refers to being proper or fitting during a situation.
• From the above options, we are able to see that three out of the four words seek advice from being acceptable or courteous. The words graceful, beautiful, and decent are the words that give this meaning. Whereas the fourth word within the group, awkward, doesn't have a meaning that falls into this category.

Hence, option C is the correct answer.
