Choose the option that best completes the gap(s).

If you want to succeed in life, don't be envious ______ other people's achievement.

Answer Details

The correct option to complete the gap is "of". This is because the sentence is talking about not being envious of other people's achievement as a means of succeeding in life. The preposition "of" is used to show the relationship between the subject ("you") and the object of the sentence ("other people's achievement").
