From the given options, select the word that is opposite in meaning to -

Culmination

Beginning

The correct answer is option 4: Beginning

The word "culmination" means the highest or final point of something, often marking its completion or climax.

 Completion – This means the act of finishing or bringing something to an end, which is similar to "culmination" rather than its opposite.

 Climax – This refers to the most intense, exciting, or important point of something, just like culmination. Again, this is a synonym, not an antonym.

 Conclusion – This means the end or final part of something, which aligns with the meaning of "culmination" rather than being its opposite.

 Beginning – This means the start or initiation of something, which is the opposite of culmination, as culmination refers to the highest or final stage.
