The task is to identify an antonym for the word 'Cajole'. To do this, we first need to understand the meaning of 'Cajole'.
Cajole means to persuade someone to do something by sustained coaxing or flattery.
Let's analyze each option:
- Deceive - This means to mislead someone into believing something that is not true. It is not a direct antonym as it involves trickery rather than persuasion.
- Mislead - This implies leading someone in the wrong direction or giving false information. It is similar to deceive and not considered an antonym for cajole.
- Build up - This suggests enhancing, increasing, or supporting something. It is not opposite in meaning to cajole.
- Bully - This means to use force, threats, or intimidation to control someone, which contrasts with the gentle persuasion implied by cajole. Therefore, bully is the correct antonym for cajole.
Thus, the correct answer is Bully.
