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 implore, beseech and entreat are synonyms of each other and these tree words have same meanings i.e. to make an earnest request to someone or to ask someone for something in an urgent way. Whereas malign means to say unpleasant and untrue things about something or someone. Hence, malign has a different meaning and it's the odd one.
